Mime doing a turn, simple clothes make possible (10)
I believe the answer is:
facilitate
'make possible' is the definition.
'facilitate' can be an answer for 'make' (thesaurus). I am not certain of the 'possible' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for facilitate that I've seen before include "Ease" , "Make easier" , "Make (something) easy" .)
