Unifying firm, ambassador is reversing victory (8)
I believe the answer is:
cohesive
'unifying' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'firm ambassador is reversing victory' is the wordplay.
'firm' becomes 'co' (a firm is a company).
'ambassador' becomes 'he' (His or Her Excellency).
'reversing' says the letters should be written in reverse.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'is' in reverse letter order is 'si'.
'co'+'he'+'si'+'ve'='COHESIVE'
Can you help me to learn more?
(Other definitions for cohesive that I've seen before include "All together, holding" , "United" , "Sticking together" , "Tending to stick together" .)
