Cry to involve Resistance in fight (5)
I believe the answer is:
brawl
'in fight' is the definition.
(I've seen this before)
'cry to involve resistance' is the wordplay.
'cry' becomes 'bawl' (synonyms).
'to involve' is an insertion indicator (inserted letters get involved).
'resistance' becomes 'r' (electronics abbreviation).
'bawl' placed around 'r' is 'BRAWL'.
(Other definitions for brawl that I've seen before include "Rowdy fight" , "Affray" , "Unruly fight" , "dispute" , "squabble" .)
