Admit money originally cut (4)
I believe the answer is:
mown
'cut' is the definition.
(past tense of 'mow')
'admit money originally' is the wordplay.
I cannot quite understand how this works, but
'admit' could be 'own' (own can mean to admit or acknowledge) and 'own' is located in the answer.
'money' could be 'm' (abbreviation used in economics) and 'm' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mown that I've seen before include "Block of cast metal" , "(Of grass) cut" , "Cut down with a blade" .)
