Predicate nouns normally appear in the nominative. But as R.Alexander says they can "on occasion appear in the instrumental". Examples: Radi kako ti se čini ispravnim. Ne želim da ispadnem sm(ij)ešnim. To ja zovem dobrim obrokom! and Opet me je žensko napravilo volom (lyric from the song Dva dinara, druže) My question is the following: Are there occasions when someone should prefer the instrumental over the nominative? Or are they more or less equivalent? (I mean, can all the previous examples be written in the nominative without changing the meaning?) Thanks again!
