Forms
rã f (plural rãs, diminutive rãzinha, augmentative rãzona)[1] Old Galician-Portuguese wrote rãa, plural rrããs and raas.[2][3] Cardoso (1569) and Barbosa (1611) write raã, Bluteau rãa.[4][5][6] Dialect forms are arrã and ran.[1][7]
Etymology
It is inherited from Latin rāna (“frog”), written Old Galician-Portuguese rãa in the oldest texts.[2][3][1] The old two-syllable form, with a nasal first vowel, later contracted to the modern one-syllable form.[2][3][1]
The same Latin word gave Galician ra, Spanish rana, Italian rana and Old French raine.[8][9][1] García de Diego also cites an old Portuguese form arraa.[9] Corominas notes that it was inherited by all the western Romance languages but soon went out of use in Catalan and Gallo-Romance.[10]
De Vaan considers the Latin noun onomatopoeic, built on a sound ⟨rā⟩, and finds a link with a root Proto-Indo-European *reh₂- (“to roar”) possible only in theory.[11]
Earliest recorded meaning
The Cantigas de Santa Maria tell of a deaf man healed so que ja oya o galo e a rãa “that he now heard the cock and the frog”.[12] Houaiss and Cunha date rãa to the 13th century.[2][3]
Semantic evolution
Bluteau (1712–1728) treats the frog as an amphibious creature, and derives its name from a Hebrew word meaning “to cry out”, after its croaking.[6] Barbosa (1611) already lists raã das moutas for a toad and cantar a raã “to croak”.[5]
In Brazil the word names several native species: Rana palmipes, eaten and called rã-verdadeira, and frogs of the genus Leptodactylus.[13][14] In Bahia it also means the tree frog or perereca.[15] In the Alentejo it is a variety of melon, and Porto Editora records a machine for compacting soil.[16][17] Cunha dates the learned derivatives from Latin: rânula (1813), ranino (1881), and ranário and ranicultura in the 20th century.[3]
