Maybe miss seeing red and green snake finally (5)
I believe the answer is:
irene
'maybe miss' is the definition.
The definition suggests a singular noun which matches the answer.
'red and green snake finally' is the wordplay.
'red' becomes 'ire' (I can't explain this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'finally' suggests the final letters.
The last letters of 'green snake' are 'ne'.
'ire'+'ne'='IRENE'
'seeing' is the link.
Can you help me to learn more?
(Other definitions for irene that I've seen before include "- - Worth, actress" , "Girl's name (meaning Peace)" , "Girl of peace" , "- - Handl, actress" , "woman" .)
