Provokes some boys following a girl (6)
I believe the answer is:
annoys
'provokes' is the definition.
The answer and definition can be both to do with human feelings as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?
'some boys following a girl' is the wordplay.
'some boys' becomes 'oys' (I can't explain this - if you can you should believe this answer much more).
'following' means one lot of letters go next to another.
'a girl' becomes 'ann' (woman's name).
'oys' after 'ann' is 'ANNOYS'.
Can you help me to learn more?
(Other definitions for annoys that I've seen before include "Irritates, bothers" , "Irks, vexes" , "'Irritates, irks (6)'" , "Hacks off" , "Irritates, vexes" .)
