Complex order of lettuce, mostly halved (6)
I believe the answer is:
cosmos
'complex order' is the definition.
The definition and answer can be both groups as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'lettuce mostly halved' is the wordplay.
'lettuce' becomes 'cos' (cos lettuce is a kind of lettuce).
'halved' suggests halving the letters.
'mostly' cut in half is 'mos'.
'cos'+'mos'='COSMOS'
'of' is the link.
Can you help me to learn more?
(Other definitions for cosmos that I've seen before include "The entire universe." , "Universe as an ordered whole" , "Universe seen as a whole" , "The universe, whole of creation" , "Universe as an ordered system" .)
