Eddy, man embracing wife and student (5)
I believe the answer is:
swirl
'eddy' is the definition.
(synonyms)
'man embracing wife and student' is the wordplay.
'man' becomes 'sir' (sir is a kind of man).
'embracing' indicates putting letters inside.
'wife' becomes 'w' (abbreviation).
'and' means one lot of letters go next to another.
'student' becomes 'L' (as in L-plates for learner drivers).
'sir' placed around 'w' is 'swir'.
'swir'+'l'='SWIRL'
(Other definitions for swirl that I've seen before include "Whirl, twirl, curl" , "Eddy, whirl" , "Turn in a twisting or spinning motion; eddy" .)
