Take the mickey out of tense relative (5)
I believe the answer is:
taunt
'take the mickey out' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'tense relative' is the wordplay.
'tense' becomes 't' (abbreviation used in many dictionaries).
'relative' becomes 'aunt' (aunt is a kind of relative).
't'+'aunt'='TAUNT'
'of' is the link.
Can you help me to learn more?
(Other definitions for taunt that I've seen before include "Gibe" , "Bait with insulting remarks" , "Sarcastic challenge" , "Make fun of" , "Guy" .)
