What does pro feta mean in latin?

Answer 1

Feta in Latin is a feminine singular adjective meaning "pregnant, full of young", "fertile" or "having just given birth". Pro means literally "in front of", but also "for" or "on behalf of". Pro feta would thus mean something like "for her who has just given birth".

A quick Google seems to reveal only one occurrence of the phrase "pro feta" in a genuinely Latin context, in the footnotes of an e-book containing early Latin hymns. The note says "plena (pro feta)", and it merely means that in one or more surviving copies of the hymn in question, the word feta is replaced by plena ("full"). In this case, pro means "for" in the sense of "in place of".

As a single word, profeta is an infrequent spelling of propheta, the Latin word for "prophet".
