Usually time left to pursue home learning (2,7)
I believe the answer is:
in general
'usually' is the definition.
(I've seen this before)
'time left to pursue home learning' is the wordplay.
'time' becomes 'lare' (I can't explain this - if you can you should give a lot more credence to this answer).
'left' says the letters should be written backwards.
'to pursue' means one lot of letters go next to another.
'home' becomes 'in' ('he's home' can mean 'he's in').
'learning' becomes 'gen' (gen can mean knowledge or information).
'lare' backwards is 'eral'.
'in'+'gen'='ingen'
'eral' after 'ingen' is 'IN GENERAL'.
Can you help me to learn more?
(Other definitions for in general that I've seen before include "More-or-less" , "Mostly" , "for the most part" , "Where soldiers should have faith" , "Overall" .)
