Better to avoid extremes in gentle stroll (5)
I believe the answer is:
amble
'gentle stroll' is the definition.
'amble' can be an answer for 'stroll' (synonyms). I'm not sure about the 'gentle' bit.
'better to avoid extremes' is the wordplay.
'better' becomes 'gambler' (a gambler is someone who bets).
'to avoid extremes' indicates the central letters (the extremes of the word are removed).
The centre of 'gambler' is 'AMBLE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for amble that I've seen before include "Walk in a leisurely fashion" , "Wander gently along" , "Blame for leisurely walk" , "Blame for slow walk" , "Take leisurely stroll" .)
