'drop' is the definition.
(thesaurus)

'a girdle over' is the wordplay.
'a girdle' becomes 'aband' (I am not sure about this - if you are sure you should believe this answer much more).
'over' becomes 'on' (physically on top of).
'aband'+'on'='ABANDON'

Can you help me to learn more?

(Other definitions for abandon that I've seen before include "Stop" , "a complete lack of restraint" , "Junk" , "Lack of constraint" , "Leave, desert" .)

I've seen this clue in The Guardian.
