Caught in constant ceasefire (5)
I believe the answer is:
truce
'ceasefire' is the definition.
(I've seen this in another clue)
'caught in constant' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'in' means one lot of letters goes inside another.
'constant' becomes 'true' (similar in meaning).
'c' put within 'true' is 'TRUCE'.
(Other definitions for truce that I've seen before include "Cruet (anag.)" , "Temporary ceasefire" , "barley" , "conciliatory agreement" , "Temporary pause in war" .)
