Many men up there in trouble without her (7)
I believe the answer is:
umpteen
'many' is the definition.
(similar in meaning)
'men up there in trouble without her' is the wordplay.
I cannot quite see how this works, but
'men' could be 'm' (abbreviation) and 'm' is present in the answer.
'up' is found in the answer.
The remaining letters 'teen' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for umpteen that I've seen before include "Guarded" , "Unspecified large number" , "Countless" , "Pet menu for a great many" , "Large but indefinite number" .)
