From Latin caper, caprum.
cabro m (plural cabros, feminine cabra, feminine plural cabras)
- male goat
- (Chile, Paraguay, colloquial, Puerto Rico) kid, boy (a child)
- (Peru, vulgar) fag (homosexual man)
- While the general rule for gender-paired nouns in Romance languages is that the male is used when the gender is unknown, the words for goat descending from the Latin capra are an exception, with the feminine form used for goats of indeterminate gender.
