'titles' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.

'look for a long time' is the wordplay.
'look' becomes 'peer' (to peer at something is to look at it).
'for' is a charade indicator (letters next to each other).
'a long time' becomes 'ages' (ages can mean a very long time).
'peer'+'ages'='PEERAGES'

'for' acts as a link.
