Out of place at home, a pint (5)
I believe the answer is:
inapt
'out of place' is the definition.
(I've seen this before)
'home a pint' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'pint' becomes 'pt'.
'in'+'a'+'pt'='INAPT'
'at' is the link.
(Other definitions for inapt that I've seen before include "Cartoon duck" , "not seemly" , "not fit for purpose" , "Not fitting" , "Unsuitable - paint (anag)" .)
