Cooler bosses struggle to attend studies (7)
I believe the answer is:
wardens
'cooler bosses' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'struggle to attend studies' is the wordplay.
'struggle' becomes 'war' (warring is a kind of struggling).
'to attend' says to put letters next to each other.
'studies' becomes 'dens' (I've seen this in another clue).
'war'+'dens'='WARDENS'
Can you help me to learn more?
(Other definitions for wardens that I've seen before include "Wanders about with guards" , "Prison officials" , "Officers in charge of prisons" , "Do they supervise" .)
