Dash to embrace wife in pain (6)
I believe the answer is:
twinge
'pain' is the definition.
(twinge is a kind of pain)
'dash to embrace wife' is the wordplay.
'dash' becomes 'tinge' (I am not sure about this - if you are sure you should believe this answer much more).
'to embrace' indicates putting letters inside.
'wife' becomes 'w'.
'tinge' placed around 'w' is 'TWINGE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for twinge that I've seen before include "Brief sharp pain" , "Sudden sharp feeling" , "Pinch" , "Emotional pang" , "Slight pain (of conscience?)" .)
