It’s not important to gossip about an award (2,6)
I believe the answer is:
no matter
'it's not important' is the definition.
(I've seen this before)
'gossip about an award' is the wordplay.
'gossip' becomes 'natter' (synonyms).
'about' means one lot of letters goes inside another.
'an award' becomes 'OM' (order of merit).
'natter' enclosing 'om' is 'NO MATTER'.
'to' acts as a link.
(Other definitions for no matter that I've seen before include "Forget it!" , "pure energy?" , "Who cares" , "It's not important - what a torment" , "Never mind" .)
