Is starting school a bit of a lark for one? (7)
I believe the answer is:
scholar
'is starting' is the definition.
I can't tell whether this definition defines the answer.
'school a bit of a lark for one?' is the wordplay.
'school' becomes 'sch' (abbreviation).
'a bit' says to take the initial letters (I've seen 'a bit of' mean this).
'a lark for one?' becomes 'lar' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'of' is 'o'.
'sch'+'o'+'lar'='SCHOLAR'
Can you help me to learn more?
(Other definitions for scholar that I've seen before include "Academic; pupil" , "university type?" , "Pupil - erudite person" , "Noted academic" , "Learned (or learning) one" .)
