Geam etymology: from Turkish cam, from Persian jām

Three languages, three shifts of sense

Four fogged panes, four dated proofs. Wipe them and read the year with its evidence.

jām Persian FA

the old sense, undated DICTIONARY

“A cup, chalice, goblet, bowl; glass…; a looking-glass, a mirror”

Steingass, p. 350

Nişanyan: the old sense “goblet, tumbler”, with an Avestan relative (yāme-). Glass and mirror already sit in the same entry.

cam Turkish TR

1330 · 1354 ATTESTED

“ele aldı cām… anı içti tamām”

Mesud b. Ahmed, 1354, in Nişanyan

“degme bir pençerede biŋ dürlü cām”: in 1330, the goblet already stands in a window (pençerede). 1354: taken in hand, drunk to the dregs. Nişanyan: the “glass” sense was gained in Persian and in Turkish.

جام the 1680 dictionary FA

1680 ATTESTED

“Scyphus, cyathus, poculum, calix, & vitrum, & speculum — Glaßscheibe, vitre”

Meninski, Thesaurus, p. 1560

One entry, the whole road: goblet, glass, mirror — and the pane, in German, French, Polish. Marked Arabo-Persian; in Turkish, glass is sırça (at Meninski).

Ottoman Turkish · the undated stage

geam Romanian RO

1805 ATTESTED

“Ca să facă noăzăci de jeamurĭ după gergevelele ce trimeasăĭ”

Iorga, S.D. VIII, p. 41 (doc. 236)

90 panes to fit the frames sent, spelled jeamurĭ, with a j. Then the lens (Alecsandri, premiered 1844) — and the whole window (DEX).

Iorga, VIII, p. 41 (scan) →

Redhouse (1890) prints the pane, and TDK keeps it today. In 1680 the sense is documented Persian; in 1805, attested Romanian. When that sense became established in Turkish remains undated. Whatever the date, the Turkish sense must predate the Romanian borrowing. RECONSTRUCTED

The document

1805: the same page

MDA2 sends both geam and cercevea to the same Iorga page — a whole order, not a coincidence.

“La Porumbac, ca să facă noăzăci de jeamurĭ după gergevelele ce trimeasăĭ… Să-m facă baglamalele de noaăsprezece ferestĭ, căte să voar putea mai zarife și țapene.”

Costandin Otetelișanu, 23 August 1805 (doc. 236) — Iorga, Studii și documente, VIII, p. 41

90 panes after the frames sent, plus hinges for 19 windows (zarife = fine, from Turkish zarif; țapene, probably sturdy). Jeamurĭ with a j; gergevele, the volume-index variant.

The volume's index: “Geamuri, 41. Cercevele (gergevele), 41.”

Letters to the Hagi Pop house; MDA2 cites the letter under both words.

The same sentence, the same order: pane and frame appear together in the document. Joint borrowing remains unproven. NOT SHOWN

The same pane, other languages

The word travels the Balkans

Five neighbours, one channel: from Persian through Turkish.

Bulgarians write the whole road

RBE: ДЖАМ “…Стъкло… на прозорец… — От перс. през тур. cam”. Of the academy dictionaries checked, the only one writing the whole road.

Serbs and Croats: regional džam

HJP: “džȁm… reg. 1. staklo 2. zastakljeno okno… tur. cam ← perz. ǧām”. Standard Serbian: no academic quote found, RMS stays to check.

Macedonians, Albanians, Greeks

Mk. џам “прозорско стакло; прозорец”, Alb. xham, several senses (both official, no etymology); Gr. τζάμι from Turkish from Persian (tertiary; noted at DER, Scriban).

The ea pattern

Cam gave geam, perde gave perdea (MDA2: 1693), çerçeve gave cercevea (MDA2: 1805), döșeme gave dușumea (MDA2: Heliade) — four DEX pairs. An observed pattern, not a rule: no dictionary states it.

What we know, what we reconstruct, what we don't

Twelve rows, each with its evidence state.

geam comes from cam ATTESTED

DEX, MDA2, DER, Scriban, Șăineanu, CADE stop here; none supports a direct loan (only Scriban notes “[d. pers.]” at the Turkish etymon).

cam comes from jām ATTESTED

TDK: “Farsça cām”; Nişanyan: from Persian, with an Avestan relative (yāme-); RBE: “От перс. през тур. cam”.

90 panes in 1805 ATTESTED

23 August 1805, doc. 236: 90 panes after the frames sent. The earliest known attestation: MDA2, confirmed on the scan; DLRLV (to 1780) does not record it; tariffs and ledgers unsearched.

they entered the language together NOT SHOWN

The same order proves they appear together, not that they entered together.

the Turkish bridge (undated) RECONSTRUCTED

1680: جام is glass and pane (Meninski, a Persian entry); 1805: geam is pane (Iorga). When the Turkish stage settled stays undated in the checked sources.

the word sticlă is old DICTIONARY

MDA2: Coresi, Tetraevanghel, p. 53 (from Slavic stǐklo) — the verse of vessels, by the reference; the text stays to verify.

the “material” sense of sticlă UNCLEAR

In DEX it is the main sense; MDA2 dates the word, not the sense. Earliest dated quote: Alexandrescu, 1863 (at DLRLC).

the jām-mirror in Romanian UNCLEAR

No attestation found: zero mirror senses in the nine Romanian dictionaries checked.

geam before 1805 UNCLEAR

Zero in Cantemir, Neculce, Țiganiada, Pann — in digital copies, not critical editions; tariffs and ledgers stay unsearched.

geamlâc comes from camlık DICTIONARY

The Turkish form: camlık (TDK; DLRM). MDA2 prints “tc. ğanlyk” — seemingly corrupt for ğamlyk; the dating (Odobescu) stands.

glass in 1653–1654, the word in 1805 ATTESTED

Windows with “glazed sashes” at Târgoviște (Engl. transl., 1836) — glass, a century and a half before the word.

geamăn is another word ATTESTED

DEX: “Lat. geminus”. Geamăn (twin) is no kin to geam (pane): one fence line, not a derivation.
