Father has time for Irishman? (3)
I believe the answer is:
pat
'irishman?' is the definition.
(Patrick is a common Irish name)
'father has time' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'has' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'pa'+'t'='PAT'
'for' is the link.
(Other definitions for pat that I've seen before include "'Light touch, on the back say (3)'" , "Touch lightly - bit of butter?" , "Light touch or stroke" , "Touch; name" , "Hit lightly" .)
