Rocket engine with discoloration in charger? (9)
I believe the answer is:
sustainer
'rocket engine' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'discoloration in charger?' is the wordplay.
'discoloration' becomes 'stain' (synonyms).
'in' means one lot of letters goes inside another.
'charger?' becomes 'suer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'stain' put inside 'suer' is 'SUSTAINER'.
'with' acts as a link.
Can you help me to learn more?
(Another definition for sustainer that I've seen is " Supporter".)
