Divide things equally, or be obliged to accept 50 (5)
I believe the answer is:
halve
'divide' is the definition.
(I know that halve is a more specific form of divide)
'equally or be obliged to accept 50' is the wordplay.
I cannot quite see how this works, but
'50' could be 'l' (Roman numeral) and 'l' is found within the answer.
'accept' could be 'have' (synonyms) and 'have' is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'things' acts as a link.
Can you help me to learn more?
(Other definitions for halve that I've seen before include "make 10 5 say?" , "Reduce by 50%" , "Bisect" , "Divide into two equal pieces" , "Divide fifty-fifty" .)
