Fond memory — larks, no end (8)
I believe the answer is:
romantic
'fond' is the definition.
(thesaurus)
'memory larks no end' is the wordplay.
'memory' becomes 'rom' (ROM is an example).
'larks' becomes 'antics'.
'no end' means to remove the last letter.
'antics' with its final letter removed is 'antic'.
'rom'+'antic'='ROMANTIC'
(Other definitions for romantic that I've seen before include "Sentimental" , "Coin mart (anag.)" , "as Darnay perhaps" , "Such a novel deals with love" , "Soulful or amorous idealist" .)
