Notice stuffed into a tent (9)
I believe the answer is:
attention
'notice' is the definition.
(I've seen this before)
'stuffed into a tent' is the wordplay.
'stuffed' is an anagram indicator.
'into'+'a'+'tent'='intoatent'
'intoatent' is an anagram of 'ATTENTION'.
(Other definitions for attention that I've seen before include "For coverage" , "Applying the mind, mental concentration" , "Special care, soldier's position" , "Keen students pay this" , "Mental concentration or awareness( 9)" .)
