Edges of Egyptian flag complete (6)
I believe the answer is:
entire
'complete' is the definition.
(synonyms)
'edges of egyptian flag' is the wordplay.
'edges of' suggests removing the centre.
'flag' becomes 'tire' (I've seen this before).
'egyptian' with its middle removed is 'en'.
'en'+'tire'='ENTIRE'
(Other definitions for entire that I've seen before include "Whole and complete" , "Envelope" , "Unmitigated" , "excluding nothing" , "Lure" .)
