Gets engaged when he is in a bit of trouble (6)
I believe the answer is:
meshes
'gets engaged' is the definition.
(I've seen this before)
'he is in a bit of trouble' is the wordplay.
I cannot quite see how this works, but
'he' is found in the answer.
'trouble' could be 'mess' and 'mess' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
'when' is the link.
Can you help me to learn more?
(Other definitions for meshes that I've seen before include "Becomes entangled or fits together" , "Co-ordinates" , "Fits into, intertwines" , "Engages with others - using nets?" , "gets engaged" .)
