Small boat from County Clare, possibly (7)
I believe the answer is:
coracle
'small boat' is the definition.
(I know that coracle is a type of small boat)
'county clare possibly' is the wordplay.
'county' becomes 'co'.
'possibly' is an anagram indicator.
'clare' anagrammed gives 'racle'.
'co'+'racle'='CORACLE'
'from' acts as a link.
(Other definitions for coracle that I've seen before include "One-man wicker boat" , "Traditional rounded boat with wicker frame" , "little boat" , "Small paddled boat" , "Welsh version of the currach" .)
