Being dishonest, engaging in folly in Galway (5)
I believe the answer is:
lying
'being dishonest' is the definition.
('lying' can be a synonym of 'dishonest')
'in folly in galway' is the wordplay.
'in' says the answer is hidden in the clue.
'LYING' is hidden within 'folly in galway'.
'engaging' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for lying that I've seen before include "telling stories" , "Prone; fibbing" , "Untruthful - in bed?" , "Deceit" , "Invention" .)
