Prior to take care of put it on (7)
I believe the answer is:
pretend
'put it on' is the definition.
I can't tell whether this definition defines the answer.
'prior to take care' is the wordplay.
'prior to' becomes 'pre' (I've seen this in other clues).
'take care' becomes 'tend' (I've seen this in another clue).
'pre'+'tend'='PRETEND'
'of' is the link.
Can you help me to learn more?
(Other definitions for pretend that I've seen before include "Imaginary, make-believe" , "Make believe - imply falsely" , "bluff" , "make a false claim" , "Suppose" .)
