Artistic style of boxer's, with rapid movement around (7)
I believe the answer is:
realism
'artistic style' is the definition.
'realism' can be an answer for 'style' (thesaurus). I am not certain of the 'artistic' bit.
'boxer's with rapid movement around' is the wordplay.
'boxer's with' becomes 'alis' (I can't justify this - if you can you should believe this answer much more).
'rapid movement' becomes 'REM' (REM is rapid eye movement in sleep).
'around' is an insertion indicator.
'alis' put within 'rem' is 'REALISM'.
'of' is the link.
Can you help me to learn more?
(Other definitions for realism that I've seen before include "True-to-life quality" , "The representation of things as they are" , "True to life quality" , "Representation in an accurate and true to life way" , "Practicality of a smiler" .)
