Others yelled regularly for transformation (7)
I believe the answer is:
'others yelled regularly for transformation' is the definition.
I can't tell whether this defines the answer.
'others yelled regularly' is the wordplay.
'others' becomes 'rest' (eg the rest of a group).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'yelled' are 'yle'.
Can you help me to learn more?
(Other definitions for restyle that I've seen before include "Model afresh" , "new design" , "Fashion anew" , "Of hair, shape in different fashion" , "make a change" .)
