A translation into Latin is needed for - 12 winters old. I can find individual words such as Hiberna for Winter and Duodecim for twelve, but I wondered if there were any students of latin out there who could help. Thank you.
Aetatis duodecim brumae - literally 'of age twelve winters' - is a possibility. However, my advice to you - based on past experience of questions involving Latin on AnswerBank - is to check with an 'expert' whatever answer(s) you get here...including mine!
For example, if your local secondary school has a Classics Department or even just a solitary Latin teacher, try to get a response from him/her. An alternative is to approach a local Catholic priest.
"Twelve winters old" is an English language idiom which cannot be translated word for word into Latin.
Probably something like " annos duodecim natus ( or nata if it refers to a female) which literally means "born twelve years". Perhaps you could use "hiemes" instead of "annos" i.e. "winters" instead of "years".
You certainly cannot use "vetus" which means "old/ancient" as opposed to" young/new".
Hope this helps - I'm dredging this up from the murky depths of my memory!
