Uproot and rip out air freshener (9)
I believe the answer is:
potpourri
'air freshener' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'uproot and rip out' is the wordplay.
'and' says to put letters next to each other.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'uproot' after 'rip' is 'ripuproot'.
'ripuproot' with letters rearranged gives 'POTPOURRI'.
Can you help me to learn more?
(Other definitions for potpourri that I've seen before include "stew" , "Bowl or jar of fragrant petals and spices" , "Mixed bag - rip up root (anag)" , "Perfumed mixture; medley" , "A medley of popular tunes" .)
