Pronunciation

Forms

ou n (plural ouă)[1]

Etymology

It is inherited from Latin ōvum (“egg”), perhaps through a Vulgar Latin form with a short vowel.[2][3][4][5][1] The Latin word comes from *h₂ōwyóm (“egg”), and is related to Ancient Greek ᾠόν (ōión).[1][6]

It survives in all four branches: Aromanian ou, Megleno-Romanian uou and Istro-Romanian owu.[2][7][8][9] Its Romance cognates include Dalmatian yuv, Italian uovo, Catalan ou, French œuf, Spanish huevo and Portuguese ovo.[2][5] The verb oua “to lay eggs” is probably directly from Vulgar Latin *ovō.[2][5]

Earliest recorded meaning

Tiktin's first record is Coresi's Pravila of about 1560.[10] Coresi's Tetraevanghel has „Sau de va ceare ou, doară va da lui scorpiie?” “or if he asks for an egg, will he give him a scorpion?” (Luke 11:12).[10] MDA2's first record is the Cuvente den bătrâni, before 1588.[4]

Semantic evolution

Old texts have the plural oauă, and regional speech ouri.[4] Beside the egg as food, the word names egg-shaped things: oul genunchiului is the kneecap, and in Oltenia oușor is the uvula.[10][3] Folk plant names use it, such as ouăle popii for hellebore.[10] In slang the plural means testicles.[2][1] Biology made it the word for the fertilized egg cell.[3][4] Ouă roșii are the red Easter eggs.[10]
