Forms
sobrinho m (plural sobrinhos, feminine sobrinha, feminine plural sobrinhas)[1] Medieval texts write sobrynn, sobrino (1306), sobrinho, sobriho, sobriño, sobrio and sonbrinho.[2][3]
Etymology
It is inherited from Latin sobrīnus (“second cousin; cousin”), written Old Galician-Portuguese sobrinno and Old Galician-Portuguese sobrino in the oldest texts.[2][3][1] The same Latin word is Galician sobriño, Asturian sobrín and Spanish sobrino.[1][4]
In classical Latin the word meant a second cousin, the son of a parent's first cousin.[5] Corominas explains the shift to “nephew” in the Iberian Peninsula: the first cousin came to be called cōnsobrīnus prīmus (whence primo), the old word was used for the more distant collateral kin, and when nepōs (“nephew; grandson”) fell out of use in the centre and west of the Peninsula it took over the sense “nephew” as well.[4][6] Nascentes notes the change of meaning.[7]
The Latin word is the noun use of Proto-Italic *swezrīnos (“of the sister”), an adjective from *swezōr (“sister”), the source of soror.[1][8] De Vaan explains the /b/ by a change of /sr/ through /fr/ to /br/, and takes the vowel of the first syllable from the word for “sister”.[8] The word for “sister” goes back to Proto-Indo-European *swésōr.[8][1]
Earliest recorded meaning
The Cantigas de Santa Maria of the 13th century have Un sobrynn' est' abadessa avia “this abbess had a nephew”.[9][2] Another cantiga speaks of un seu sobrinho que aqui chegou “a nephew of his who came here”.[10] The sense is already “a brother's or sister's son”.[9][2]
Semantic evolution
The meaning has not changed since the medieval texts, but the Latin equivalent puzzled the lexicographers: Cardoso (1569) rendered sobrinho with Latin nepos, and Barbosa (1611) objected that Cicero and the ancients did not use nepos so, proposing filius fratris and filius sororis.[11][12] Bluteau repeated the objection, citing Vossius.[13] The compounds sobrinho segundo and sobrinho-neto name the son of a nephew or niece.[2][14] Nascentes records Sobrinho as a surname given to someone who bears the same name as an uncle.[15]
