50 percent with time for female in end (4)
I believe the answer is:
halt
'end' is the definition.
(synonyms)
'50 percent with time for female' is the wordplay.
I cannot quite understand how this works, but
'50' could be 'l' (Roman numeral) and 'l' is found in the answer.
'time' could be 't' (abbreviation) and 't' is located in the answer.
The remaining letters 'ha' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for halt that I've seen before include "game" , "Limp; minor station" , "Cease" , "limping" , "Falter - stop" .)
