Girl involving one in love entanglement (5)
I believe the answer is:
olive
'girl' is the definition.
(girl's name)
'one in love entanglement' is the wordplay.
'one' becomes 'o' (I've seen this in other clues).
'in love entanglement' becomes 'live' (I am not sure about this - if you are sure you should believe this answer much more).
'o'+'live'='OLIVE'
'involving' acts as a link.
Can you help me to learn more?
(Other definitions for olive that I've seen before include "It's branch is a symbol of peace" , "Fruit giving oil" , "Oil-producing fruit" , "Fruit; Popeye's girlfriend" , "One [TYPE OF TREE] is from the Mediterranean" .)
