Weepy, getting reprimand after start of trouble (7)
I believe the answer is:
tearful
'weepy' is the definition.
(similar in meaning)
'reprimand after start of trouble' is the wordplay.
'reprimand' becomes 'earful' (earful is a kind of reprimand).
'after' means one lot of letters go next to another.
'start of trouble' becomes 't' (I can't explain this - if you can you should give a lot more credence to this answer).
'earful' after 't' is 'TEARFUL'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for tearful that I've seen before include "Weepy" , "Inclined to cry" , "Visibly upset" , "Lachrimose" , "emotional" .)
