Squabbling in a boat? (6)
I believe the answer is:
rowing
'a boat?' is the definition.
(rowing boat is a kind of boat)
'squabbling in' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rowing that I've seen before include "Sculling sport?" , "Sport associated with Henley" , "Aquatic sport" , "Using oars" , "Olympic sport; arguing" .)
