пеперуда

From Proto-Slavic *perperǫda, *perperǫga, *perperuxa, *perperica, of disputed origin:

• Mladenov: Derived via reduplication from Proto-Slavic *perti, *pьrati (“to fly, to propagate”) or *pero (“feather”).
• Meyer: Wanderword, akin to Latin papīlio (“butterfly”), Romanian paparugă (“ladybug”), Italian parpaglione (“butterfly”), possibly of onomatopoeic nature.
• Ultimately derived from Proto-Kartvelian *p̣erp̣er- (“butterfly”).

The ending has been compared to the suffix of Greek πεταλούδα (petaloúda, “butterfly”), itself of unclear origin.

• IPA^(key): [pɛpɛˈrudə]

пеперу́да • (peperúda) f (related adjective пеперу́ден, diminutive пеперу́дка)

1. butterfly (daytime lepidopterous insect of superfamily Papilionoidea)
2. (by extension) type of embroidery ornament
3. (figuratively) fly-by-night
4. (regional) flower of family Iridaceae

   Synonyms: перуни́ка (peruníka), (Turkism) сале́п (salép)

5. (folklore) Perperuna (custom for evoking rain, common throughout the Balkans)

   Synonyms: перуница (perunica), преперуша (preperuša), додола (dodola)

The relation between the meaning “butterfly” and the name of the folk custom is uncertain. The later is sometimes associated with the pagan Slavic deity Perun, which may or may not be etymologically related.
