Time and relaxation needed for rib (5)
I believe the answer is:
tease
'for rib' is the definition.
(thesaurus)
'time and relaxation' is the wordplay.
'time' becomes 't'.
'and' means one lot of letters go next to another.
'relaxation' becomes 'ease' ('ease' can be a synonym of 'relaxation').
't'+'ease'='TEASE'
'needed' is the link.
(Other definitions for tease that I've seen before include "Playfully provoke" , "Make playful fun of (someone)" , "Page of book" , "Vex" , "Josh" .)
