Sounds rising round solicitors leader during sitting (7)
I believe the answer is:
session
'sitting' is the definition.
(eg a parliamentary session)
'sounds rising round solicitors leader during' is the wordplay.
'sounds' becomes 'noises' (noise is a kind of sound).
'rising' shows that the letters should be reversed in order (going up in a down clue).
'round solicitors leader' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'during' is an insertion indicator.
'noises' back-to-front is 'sesion'.
'sesion' placed around 's' is 'SESSION'.
Can you help me to learn more?
(Other definitions for session that I've seen before include "Time in legislature" , "Meeting of a court or parliament" , "Period during which a group meets" , "School term" , "Meeting or series of meetings" .)
