Before date, naked lady put on top (3)
I believe the answer is:
add
'on top' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'before date naked lady' is the wordplay.
'before' means one lot of letters go next to another.
'date' becomes 'd' (abbreviation e.g. dob - date of birth).
'naked' indicates the central letters (outside letters removed so centre is unclothed).
The centre of 'lady' is 'ad'.
'd' after 'ad' is 'ADD'.
'put' acts as a link.
Can you help me to learn more?
(Other definitions for add that I've seen before include "Give more" , "Put together - attach" , "Put together (numbers)" , "Total; put together" , "Put together - append" .)
