Square meal not half awkward in tents (8)
I believe the answer is:
marquees
'tents' is the definition.
(marquee is a kind of tent)
'square meal not half awkward' is the wordplay.
'not half' indicates taking half.
'awkward' indicates anagramming the letters.
'meal' cut in half is 'me'.
'square'+'me'='squareme'
'squareme' is an anagram of 'MARQUEES'.
'in' is the link.
(Other definitions for marquees that I've seen before include "Very large tents" , "Very large tent, for circuses etc." .)
