WHERE DOES THE WORD “RUSALII” COME FROM?
From the roses of Rome to Pentecost
The Romanian name of Pentecost goes back, ultimately, to Latin Rosalia, the name of rose celebrations. But the modern form Rusalii does not descend from Latin in any simple, demonstrable way: scholars have debated a route through Medieval Greek and Slavic, as well as an inherited Latin form later reshaped under Slavic influence.
- 50 DAYS
- after Easter falls the Descent of the Holy Spirit — Pentecost
- AD 138
- an annual rose celebration recorded at Histria
- TWO ROUTES
- possible from Latin to Romanian — both debated
How the word changes shape, from Rome's May to today:
- ROSALIA Latin
- ΡΟΥΣΑΛΙΑ Medieval Greek
- рѹсалиѩ Slavonic
- ROSALII Old Romanian
- RUSALII Romanian
The sources agree on the distant origin but not on the whole route. The very gap between the attested forms is what makes the etymology interesting — and its Romanian endpoint has three lives: feast, fairy, mayfly.
THE FEAST
The Descent of the Holy Spirit, 50 days after Easter. “Duminica mare.”
THE FAIRY
A supernatural being, like the iele: storms, crippled people, lost minds.
THE MAYFLY
A mayfly larva from the Danube's waters; the dictionaries disagree on the species.
You say all three when you say Rusalii.
I · THE ROMAN WORLD
The roses of Rome
Rosalia was not necessarily one empire-wide festival held everywhere on the same day. The sources attest several rose celebrations, in funerary, associative, public and military contexts, mostly in May and June.
Four witnesses, from Histria to Capua
- AD 138HISTRIARhodismos: an annual rose celebration, funded by decree.
- 224–235DURA-EUROPOSRosaliae signorum: rose garlands for the standards.
- 354ROMEMacellus rosa sumat: roses reach the market on 23 May.
- 387CAPUARosaria amphitheatri: the amphitheatre's roses, on 13 May.
The first rite: flowers on graves
In May and June the Romans laid roses — and violets — on graves: flowers for the dead, wine and food for the living. A banquet shared with them, not a commemoration in the modern sense.
The Calendar of Filocalus, of 354, notes the roses coming to market on 23 May — macellus rosa sumat — in a month crowded with rose feasts and rose imagery.
At Capua, an inscribed calendar of 387 enters rosaria amphitheatri on 13 May — the roses of the amphitheatre. Market, graves, amphitheatre: one custom, several stages.
The second rite: garlands on standards
Also in May, the Roman army decked its standards (signa) with roses, in a public supplication (supplicatio): the Rosaliae signorum, the rose-feasts for the standards.
The feast appears in the Feriale Duranum, the papyrus calendar of a cohort stationed at Dura-Europos, from the reign of Severus Alexander (224–235).
Of the two May dates, the first is uncertain — the papyrus text is fragmentary — and probably falls on 10 May; the second is 31 May. The historian Hooey reads them as spring festivals of vegetation, not as a commemoration in the modern sense.
MAY: roses on graves, garlands on standards — two rites, one month.
II · THE WORD
The word travels
Latin Rosalia stands at the origin of the family of forms. But exactly how the modern Romanian form Rusalii got here stays debated: the nodes below are attested forms, the arrows are proposed or disputed links — and philologists have debated two routes, not one.
Two routes, not one arrow
Route A is the usual indirect explanation, through Greek and Slavic. Route B starts from the old and regional Romanian forms, later reshaped under Slavic influence.

- A solid arrow (→) is a proposed link.
- A broken arrow (⇢) is a disputed link.

The word's variants
- rosalii the old form, with o (MDA2)
- rusale the western form (Scriban, 1939)
- rusare a regional form (in Bălteanu, after Babeu)
- rusalii today's form
MDA2 also notes the strat de Rusalii (the Rusalii “stratum”): a feast 24 days before Rusalii. The word had a before; its exact route stays to be reconstructed.
Two routes, one starting point: Rosalia. From here the page moves to the week in which the word lives today.
III · THE WEEK
The week between worlds
Between Saturday and Sunday crowd memorial alms, green branches and fairies. Customs vary by place and village; what follows separates church practice from dictionary testimony and folk belief.
THE SATURDAY
the graves
On Rusalii Saturday, vessels full of wine and food crowned with flowers are shared for the dead — a very old custom, writes Șăineanu in 1929. Scriban adds: on the Saturday before Rusalii, memorial alms for the dead are given in places.
THE SUNDAY
the church
On Sunday, green branches are shared at church. Scriban recorded walnut branches in 1939; a 1945 photograph shows churches dressed in “holy” linden at Moldovița, while at Timișoara the cathedral dresses in oak — the custom varies by place.
THE WEEK
the waters and the dance
In folk belief, the Rusalii are also fairies of waters and air, raising storms (DEX, MDA2: syn. iele, drăgaice). Șăineanu also notes the saying l-au umflat Rusaliile — the Rusalii have left him swollen.
In the same week: the Căluș
The Căluș ritual is inscribed on the UNESCO list in 2008 (proclaimed in 2005): all-male Călușari dancers in the Olt region, with two violins and an accordion; the name comes from căluș, the wooden part of the horse's bridle.
The oldest documented music is from the 17th century, and the origins — probably ancient purification and fertility rites — carry UNESCO's own “probably”. The Călușari still gather on Rusalii Sunday: a side story, not a link in the etymology.
IV · TODAY
Two names, two memories
Romanian has two names for the same feast: one that counts, one that remembers the roses. Here they are as the dictionaries define them.
Cincizecimea · the name that counts
The event and feast of the Descent of the Holy Spirit, 50 days after Christ's Resurrection. The dictionary gives the etymology too: Cincizeci + the suffix -ime.
Rusalii · the name that remembers the roses
The feast of the Descent of the Holy Spirit, of most ancient mythological origins, from rites of remembrance of the dead — and also, fairy and mayfly. DEX again.
The 50-day count: paste-pesach →
“On Rusalii Saturday, vessels full of wine and food crowned with flowers are shared for the dead.”
We chose the fragment from the dictionary: one line of old language, not a whole tale.
The rose left Romanian no ordinary word for the flower: trandafir comes from Greek, roz from French. But Rosalia left its name to a feast — by a road philologists are still reconstructing.
Three things that are not true
Each denial stands on its source.
“'Rusalii' directly continues Latin Rosalia.” TOO SIMPLE: a straightforward regular derivation is problematic — the l that should have vanished, rosalii with o. Most dictionaries give Slavonic rusalija as the immediate source, while other scholars have proposed an inherited Latin form, later reshaped under Slavic influence.
“'Rusalii' is the Holy Spirit's name.” NO: it is the feast's name — the day of the Descent of the Holy Spirit, 50 days after Easter (DEX). The roses named Pentecost, not the Person.
“The rusalka has a fish tail.” NO: the Slavic rusalka is not simply the Western mermaid's twin. Across much of the folk tradition she is anthropomorphic, with legs; the fish-tailed woman grows familiar only in late literary and popular images (Kononenko 2007).
The evidence ledger
What is attested, what is reconstructed, and where the hypotheses part ways.
WHAT WE KNOW
- Latin Rosalia / Rosaria is attested, and the rose rituals are well documented.
- The related Byzantine and Slavic forms are attested.
- Old Romanian Rosalii is attested, as are the regional Rusale and Rusare.
- Modern Romanian has all three senses: feast, supernatural being, insect.
WHAT IS RECONSTRUCTED
- The exact transmission route between Latin, Byzantine Greek, Slavic and Romanian.
WHAT STAYS DISPUTED
- Whether Romanian inherited an early Latin form, later reshaped under Slavic influence.
Questions
Where does the word Rusalii come from?
From the Latin Rosalia family, the name of Roman rose celebrations — but the exact route into Romanian is disputed: through Medieval Greek and Slavic, or from an inherited Latin form reshaped later.
What do the Rusalii have to do with roses?
The Christian feast's name may keep the name of Rome's rose celebrations. An inscription from Histria, of AD 138, even records an annual rose celebration — without proving continuity into Romanian.
Does Rusalii come straight from Latin?
Not by a straightforward regular derivation: the kept l and the old rosalii with o resist a simple account. Dictionaries usually give Slavonic rusalija as the immediate source; direct inheritance with later Slavic reshaping stays debated.
What does Cincizecime mean?
The feast of the Descent of the Holy Spirit, 50 days after Easter — the name that counts, beside Rusalii, the name that remembers the roses.
What are the Rusalii of folklore?
Water-and-air fairies of folk belief, akin to the iele — a sense developed later from the feast's name, not the other way round: the feast is not dedicated to them.
Why is an insect called a “rusalie”?
Danube fishermen gave that name to the mayfly larvae in the riverbanks, a prized bait; Șăineanu noted that the larvae appear as complete insects around Rusalii day. The dictionaries identify the species differently, so the name stays a popular one, not a taxonomic one.
