Talk:seu

Seu isn't familar only, I can use the term with persons I'm not acquainted, for example addressing them an insult. --João Neto (talk) 19:41, 1 February 2013 (UTC)

That’s the determiner definition. — Ungoliant ^(Falai) 20:18, 1 February 2013 (UTC)

There it is translated you when it means mister literally. --João Neto (talk) 20:23, 1 February 2013 (UTC)

You’re only looking at part of the entry. Both definitions are there:

Determiner
seu m (plural seus, feminine sua, feminine plural suas)
   you (used before epithets for emphasis)
       Seu idiota!
           You idiot! (addressing one man)
       Suas idiotas.
           You idiots! (addressing a group of women)

and

Noun
seu m (usually uncountable)
   (familiar) mister (as a form of address)

Has a strange split over there. --João Neto (talk) 20:27, 1 February 2013 (UTC)

You should be right, anyway, seu as appearing there sounds vocative in my ears.--João Neto (talk) 22:12, 1 February 2013 (UTC)
