Paintings seen in Dumbarton (3)
I believe the answer is:
art
'paintings' is the definition.
(painting is a type of artwork)
'in dumbarton' is the wordplay.
'in' indicates a hidden word.
'ART' can be found hidden inside 'dumbarton'.
'seen' acts as a link.
(Other definitions for art that I've seen before include "Works in a gallery" , "Skill, craft" , "Works of beauty created by humans" , "Beautiful or significant products of human creativity" , "Works of creative imagination" .)
