Looked for noble man (6)
I believe the answer is:
peered
'looked' is the definition.
(peering is a kind of looking)
'noble man' is the wordplay.
'noble' becomes 'peer' (peers are members of the nobility).
'man' becomes 'ed' (short for Edward).
'peer'+'ed'='PEERED'
'for' is the link.
(Other definitions for peered that I've seen before include "Looked through narrowed eyes" , "Looked closely" , "Having been made a Lord < examined" , "Look searchingly" , "Looked searchingly" .)
