Fashionable guy — he trips over (7)
I believe the answer is:
hipster
'fashionable guy' is the definition.
The definition suggests a singular noun which matches the answer.
'he trips over' is the wordplay.
'over' is an anagram indicator.
'he'+'trips'='hetrips'
'hetrips' is an anagram of 'HIPSTER'.
Can you help me to learn more?
