Put in a request for caretakers to cut terrace (3)
I believe the answer is:
ask
'put in a request' is the definition.
'ask' can be an answer for 'request' (thesaurus). I'm not certain of the 'put in a' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ask that I've seen before include "Inquire" , "Issue invitations" , "Something demanded" , "Put a question" , "Request, invite" .)
