Terrible losers I'd find in the Army (8)
I believe the answer is:
soldiers
'terrible losers i'd find in the army' is the definition.
I can't tell whether this definition defines the answer.
'terrible losers i'd find in the' is the wordplay.
'terrible' is an anagram indicator.
'find' indicates an anagram.
'in the' is an insertion indicator.
'id' is an anagram of 'di'.
'losers' is an anagram of 'solers'.
'solers' placed around 'di' is 'SOLDIERS'.
Can you help me to learn more?
(Other definitions for soldiers that I've seen before include "[TOAST] divided up" , "Military personnel" , "More than one fighter" , "Army fighters" , "Strips of toast for egg dipping" .)
