Cockney got love from East End girl (5)
I believe the answer is:
linda
'end girl' is the definition.
'Linda' can be an answer for 'girl'. I'm unsure of the 'end' bit.
'cockney got love from east' is the wordplay.
'cockney got' becomes 'ad' ('had' - having is a kind of getting - said with the 'H' dropped - a cockney accent.).
'love' becomes 'nil' (I've seen this before).
'from east' is a reversal indicator.
'ad'+'nil'='adnil'
'adnil' back-to-front is 'LINDA'.
Can you help me to learn more?
(Other definitions for linda that I've seen before include "23 [LOVELACE]" , "-- Gray, 'Dallas' star" , "- Ronstadt, US singer" , "girl" , "Girl's name (I, not Y)" .)
