AN EXCAVATION IN THREE WORDS
The village was once a ditch
More precisely: the word “sat” is explained by the dictionaries through Latin fossatum, “ditch”. How a ditch came to mean a settlement — with the old form fsat, the fortress that used to be a city, and the city-word borrowed from Hungarian — is the story below, with the documents in view and the reconstructions marked.
- fossatum → sat
- the standard etymology; “fortified settlement” is a reconstructed stage
- civitas → cetate
- Latin inheritance; the meaning narrowed to fortress
- város → oraș
- Hungarian borrowing; entry date unknown

One word, four ages:
- FOSSATVM Latin: ditch, trench
- *fortified settlement reconstructed sense
- fsat Old Romanian, early 16th c.
- sat today: village
sat < fossatum · cetate < civitas · oraș < város per DEX; one etymologist dissents
The ditch, the legion's infrastructure
The ditch was standard technology for a Roman camp — but not to a single template, every evening, everywhere. Polybius describes the Republican army (2nd century BC); Vegetius, a late military treatise (late 4th century AD), gives two ditches according to danger.
“The Greeks, in encamping themselves, consider it of the first importance to adapt the camp to the natural advantages of the ground, firstly, because they shirk the labour of entrenching… Whereas the Romans prefer to undergo the toil of entrenching and other defensive work, for the sake of having one sort of camp which never varies and is familiar to all.”
The division of labour is in 6.34 (the allies dig two sides, the Romans the other two); the Greek comparison is in 6.42. Both quoted from the Loeb edition — describing the Republican army, not one timeless Rome.
The dimensioned ditch — according to danger
The light ditch: 9 × 7 feet
“tumultuaria fossa fit lata pedes nouem et alta pedes VII” — when “nimia necessitas non premit”, when no pressing need weighs: 9 feet broad and 7 deep (≈2.7 × ≈2.1 m).
The full ditch: 12 × 9 feet
“legitima fossa… XII pedes lata sit et alta… pedes nouem” — where “uis acrior inminet”, where a keener enemy threatens: 12 broad, 9 deep (≈3.6 × ≈2.7 m). Both dimensions sit in 1.24; recommendations, not site measurements.
Roman feet, not modern ones
The conversion uses the accepted modern value once, 1 pes = 296 mm. Vegetius gives feet only; the metres are our arithmetic, with the factor in the open.
Method: archaeologists still classify these ditches by profile — “fossa fastigata”, the V-section ditch. The 2024 Ermelo dig (Netherlands) cites Vegetius 1.24 and Pseudo-Hyginus §50 as the ancient authorities for the dimensions.

The ditch at continental scale
In North Africa the Romans took the ditch to frontier scale: the Fossatum Africae — one or more linear defence systems. It is claimed to extend over 750 km or more — a length to treat with care, since the source itself says “claimed”.
The reference is our own arithmetic (haversine) from the two towns' coordinates; the top bar renders the source's claim, with “claimed” glued to the number.
The single ancient mention, with an exact number
Fossatum is named once in pre-20th-century historical literature: the law of 29 April 409 from emperors Honorius and Theodosius II to Gaudentius, vicar of Africa — CTh 7.15.1 — on maintaining the limes and the fossatum, raised, says the text, by “the ancients”.
Baradez's map
The extent only became known after World War II, from aerial photographs: Jean Baradez mapped at least four segments, and his survey remains foundational — the map below is “after Baradez (1949)”.
Dating: centuries of work
“It is not known with certainty when the Fossatum was constructed”: digs along the route give dates from Hadrian (2nd c.) to Constantine (4th c.). Baradez proposed a start after Hadrian's first African visit, in 122; he also postulated a building pulse under Gordian III and abandonment around 430–440. Attributions, not certainties.

The rupture: the 270s
The traditional date for Dacia's official abandonment is 271 — but another view moves the evacuation to 272–273, possibly as late as 275. Read it as “the 270s”: the withdrawal of Roman administration and army from north of the Danube under Aurelian. The fate of the Romanized population became mired in controversy.
“The province of Dacia, which Trajan had formed beyond the Danube, he gave up, despairing, after all Illyricum and Moesia had been depopulated, of being able to retain it. The Roman citizens, removed from the towns and lands of Dacia, he settled in the interior of Moesia, calling Dacia that which now divides the two Moesias.”
A new province, in the south
Aurelian created a new province called Dacia south of the Danube — Dacia Aureliana — with its capital at Serdica. Eutropius places it “in media Moesia”, between the two Moesias; modern descriptions vary from page to page — so this page goes no further than Eutropius's wording.
The controversy stands
The “Controversy over the fate of the Daco-Romans” section sets two theories against each other — continuity of a Daco-Roman population north of the Danube, or a near-total pullback. The camps stay facing each other; the thread followed here is the words', not continuity's.
Why it matters for words
Between the fort digging the ditch and the village inheriting its name lies this rupture — as background, not proof. An inherited word proves linguistic filiation; it does not say by itself where every generation of speakers lived.



The meaning engine
From AD 100 to today, four tracks — but not every node is the same kind of thing: some are source forms, some dated attestations, one a reconstruction, the last ones modern forms. FOSSATUM slides toward village, CIVITAS toward fortress, VÁROS enters late, from outside — while the western control, fossé/fossato, never leaves the ditch.
- ETYMON — the source form the word descends from
- ATTESTED — the form occurs in a surviving text
- RECONSTRUCTED — a stage linguists infer; its scale position is schematic
- MODERN FORM — today's dictionary; the year is a scale convention

Pick a year on the centuries' scale; press a node to jump to its year.
Method: every node wears its type in the open. Modern forms sit at 2009, the year of DEX '09; the “100” (Latin), “1200” (medieval Hungarian) and “1000” (reconstruction) positions are scale conventions, not dates. The “270” tick is historical context — the Aurelianic withdrawal — not an attestation.
The evidence, as museum pieces
Three dictionary entries, set side by side. Each is a labelled piece: what it says, how old the dictionary is, what it does not prove.
sat
DEX '09 + MDA2
“SAT, sate, s. n. 1. Așezare rurală […] – Lat. fossatum.” MDA2 adds the full header: the cited attestation is PSALT. HUR. 462/11, the old variant is fsat, and the etymology reads “ml fossatum «șanț» cf alb fshat” — “ml” means “inherited from Latin”, and “cf” points at Albanian fshat.
cetate
DEX '09 + MDA2 + CADE + Șăineanu + DER
“CETATE, cetăți, s. f. 1. Loc întărit […] fortăreață. […] – Lat. civitas, -atis.” But MDA2 also records urban senses (6–9: fortified town, large town), CADE gave sense 1 as “Oraș”, Șăineanu (1929) wrote “walled fortified town, town in general, today only in poetry”, and DER lists “1. Fortress… 2. Town.” The narrowing shows by setting dictionaries side by side — not by dating senses one after another.
oraș
DEX '09 + MDA2
“ORAȘ, orașe, s. n. 1. Formă complexă de așezare umană […] – Din magh. város.” MDA2 cites the 1521 attestation (HURMUZAKI, XI, 843), the old variant ur- and the same etymology — “mg város”. The first surviving attestation is not the word's entry date into the language.
The senses of sat recorded by MDA2
- 1(Înv) Cortold sense
- 2(Înv) Locuință (rudimentară)old sense
- 3(Pex) Așezare umană compusă din corturirecorded sense
- 4(Sens curent) Așezare umană ruralăcurrent sense
- 9(Înv) Cetateold sense
- 14(Înv) Sanctuarold sense
- 15(Înv) Ogorold sense
The numbering is the dictionary's — and number order does not prove the order of appearance: DER, for one, puts “Câmp, ogor” (“field”) first. Senses 5–8 and 10–13 (inhabitants, phrases, modern senses) are skipped here.
The one who doubts
The Dicționarul etimologic român (Cioranescu, 1958–1966) files the origin of sat under “Origine îndoielnică” (“doubtful origin”) — after listing the fossum camp (Bogrea, Tiktin, Daicovici, Candrea, Scriban, Rosetti) and the Albanian route (Cihac, Meyer, Densusianu…). His preference: Latin sătum. He gets the floor at length — including the concession that keeps this page on the majority's side.
For sătum (DER)
- “One should rather start from Latin sătum, from sĕro ‘to plant, to sow’” — an explanation that fits, says DER, sat's first 16th-century senses.
- The starting idea would be “seniorie” or “moșie” (“lordship”, “estate”), onto which the lord's subjects settled — at first “a mere plantation, as in the old colonies”; compare Slavic sadŭ “plant” → selo “village”.
- The explanation had already been given by Cipariu (Gram., 205).
Against sătum (DER again)
- “…would be sufficient, were it not for the proof of the old form fsat, difficult to explain.” The concession is Cioranescu's own — and it is this panel's hinge.
- One might suppose a confusion, already in Latin, between sătum and fossatum; “but even so the phonetic difficulties remain.”
- DER rejects the other proposals too: “Der. from Latin fixatum (Giuglea) is improbable, and even more so the one from Latin *massatum (Meyer 111).”
- Meanwhile today's dictionaries (DEX, MDA2) and modern syntheses hold fossatum — with “fortified settlement” as a reconstructed stage, not an attested Latin sense.
No verdict beyond that: today's standard etymology is fossatum; its history was not unanimous — and the fsat form remains the constraint every proposal must explain.

1521 is not the beginning of written Romanian — read why in “Neacșu's letter”.
Same ancestor, two afterlives
The true experiment starts from Late Latin fossatum — the same starting point. In Romanian it becomes sat; in French it stays fossé, “ditch”; in Italian, fossato. Same root: French kept the ditch, Romanian kept the settlement. Alongside, cousins from Latin's other branch, fossa: English fosse and Spanish foso, via Italian.
fossé (French)
“du lat. fossatum, de fossa, fosse” (Littré). Modern senses: “ditch; trench; moat”. No village in sight — just the ditch, kept.
fossato (Italian)
“dal lat. tardo fossatum… propriam. part. pass. del v. fossare” (Treccani): drainage ditch; in fortifications, the perimeter ditch. The same conservatism.
fosse (English)
“ditch, trench”, early 14th c., from Old French fosse (12th c.), from Latin fossa — the other branch. Fosse-way probably takes its name from the roadside ditch.
foso (Spanish)
“Borrowed from Italian fosso. Cognate with English fosse.” A learned borrowing via Italian — hence “cognate”.



The borrowed word
Romania's urban vocabulary is layered, not replaced piece by piece: cetate from Latin, târg from Slavic, oraș from Hungarian. The words coexist, overlap, specialise — oraș did not enter a void.
What we know
MDA2 records the 1521 attestation and the “mg város” etymology; DEX confirms the borrowing. Hungarian város is tied to vár, “fortress, castle”. That is all.
It did not enter a void
târg — from Slavic trŭgŭ (DEX) — also means “smaller urban settlement”; DER gives sense 4 as “Oraș, orășel”, and MDA2 cites COD. VOR. 100/15. When oraș enters, târg is already there.
What we don't know
When város entered Romanian and by which route. The 1521 attestation is only a “no later than” — the word may be older than the oldest surviving paper.
A real ditch, an uncertain date
In Wallachia and Oltenia, ditched earthen ramparts still show — Brazda lui Novac. The perfect case for this page's method: the ditch physically exists, but dating and function differ by segment and by source. We spread the disagreement and draw no conclusion — contextual archaeology, not etymological proof.
The disagreement, briefly
The English version: a Drobeta–Ploiești vallum, 3 m high, 2 m ditch; datings from the 1st century (Donat) to 322 (Constantine). The Romanian version: a 4th-century Constantinian northern Brazda; a southern Brazda — the Troianul — with different dimensions and datings (2nd–3rd centuries, now Augustus, now Hadrian).
The interim verdict
“Datarea valului de pământ Brazda lui Novac de sud este încă neclară și mult discutată” — the dating of the southern vallum is still unclear and much discussed. Physical survival does not make interpretation easy: not even a ditch hundreds of kilometres long dates itself precisely.


And today's village
Tell the story in one breath — the word “sat” comes from “ditch”, “cetate” from “city”, “oraș” from Hungarian — and add the hedge that makes all the difference: dictionaries say confidently where words come from; when, where and why each meaning turned remains, in parts, reconstructed.

What we don't know (and say so)
- The first Romanian attestations of cetate and oraș. This page cites only MDA2's recorded attestations (COD. VOR. and 1521 respectively) — and 1521 is a “no later than”, not the word's birthday.
- Which medieval charters might document the villa/oppidum/civitas vocabulary. Unconfirmed leads: the Andreanum, the Ioannites' Diploma — no text quoted until verified.
- Whether villages ever dug their own defence ditches (the obște). The claim stays off the page until a primary or archaeological source.
- The exact fsat passage in the Hurmuzaki Psalter (MDA2 cites 462/11). Until the edition is checked, the page cites the reference, not the verse.
- Who is right about continuity. A journey of words has no standing to settle it — and this page does not use the 270s withdrawal as etymological proof.
Quiz: what we know vs what we reconstruct
Six questions about the distinctions that matter: attested versus reconstructed, dictionary versus chronology, word versus thing.
question 1 of 6
MDA2 gives the old variant “fsat” — and DER, though it prefers sătum, concedes it is “difficult to explain”. What does fsat give us?
A form, not a photograph: fsat preserves an old consonantal stage — which is why DER itself stops at it. This page holds fossatum, with the dissent in view.
question 2 of 6
MDA2 puts the sense “Cort” (“tent”) first; DER puts “Câmp, ogor” (“field”) first. What does sense order in a dictionary prove?
Only organisation: two dictionaries, two orders. Chronology needs dated attestations, not sense numbers.
question 3 of 6
Littré: fossé “du lat. fossatum”. Treccani: fossato “dal lat. tardo fossatum”. What does the pair show?
Semantic drift made visible: same root, two afterlives — the West kept the ditch, Romanian kept the settlement.
question 4 of 6
DEX: târg, sense 3 — “smaller urban settlement”, from Slavic. Did oraș enter a void?
No: the urban vocabulary was layered — cetate, târg, oraș — and the words specialised through coexistence, not scheduled replacement.
question 5 of 6
The Saalburg photo documentation: “Both the ditches belong to the late period of the fort… reconstructed over the Roman foundations”. What does the image show?
A permanent fort, late period, walls rebuilt over Roman foundations — archaeological context for what a fossatum was, not proof of the every-evening ditch.
question 6 of 6
Sat < fossatum is an inherited etymology. Does it say where all the speakers lived in AD 700?
No: an inherited word proves linguistic ancestry, not each generation's address. The 270s are context, not etymological proof.
