Stop my manoeuvre with minute indication (7)
I believe the answer is:
symptom
'indication' is the definition.
(symptom is a kind of indication)
'stop my manoeuvre with minute' is the wordplay.
'manoeuvre with' is an anagram indicator.
'minute' becomes 'm' (abbreviation).
'stop'+'my'='stopmy'
'stopmy' anagrammed with 'm' makes 'SYMPTOM'.
(Other definitions for symptom that I've seen before include "It alerts one to illness" , "Sign of illness" , "Sign; indication" , "Sign of disease" , "Expression" .)
