Slog from left-handed opener breaking school record (6)
I believe the answer is:
schlep
'slog' is the definition.
Both the answer and definition are verbs in their base form.
Maybe there's an association between them I don't understand?
'left-handed opener breaking school record' is the wordplay.
'left handed opener' becomes 'l' (I can't explain this - if you can you should believe this answer much more).
'breaking' indicates putting letters inside.
'school' becomes 'sch' (common abbreviation).
'record' becomes 'EP' (abbreviation for extended play record).
'sch'+'ep'='schep'
'l' placed within 'schep' is 'SCHLEP'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for schlep that I've seen before include "clumsy individual" , "Clumsy and stupid person" , "Tedious or difficult journey" , "stupid and incompetent person" , "[TURKEY] -- > difficult procedure" .)
