Man in tangle gets engaged (6)
I believe the answer is:
meshes
'gets engaged' is the definition.
(I've seen this before)
'man in tangle' is the wordplay.
'man' becomes 'he' (he refers to a man).
'in' indicates putting letters inside.
'tangle' becomes 'mess' (I've seen this in another clue).
'he' inserted inside 'mess' is 'MESHES'.
(Other definitions for meshes that I've seen before include "Fits into, intertwines" , "Becomes entangled or fits together" , "gets engaged" , "Co-ordinates" , "Engages with others - using nets?" .)
