Mimic has to leave the ground (4,3)
I believe the answer is:
take off
I believe this is a triple definition!
'mimic' is the first definition.
(I've seen this before)
'has' acts as a link.
'to' is the second definition.
(thesaurus)
'leave the ground' is the third definition.
(I've seen this before)
(Other definitions for take off that I've seen before include "Split" , "fly" , "Mimic - leave the ground" , "Act of mimicry" , "Get into air" .)
