Give speech at venue where students have assembled (7,7)
I believe the answer is:
lecture theatre
'venue where students have assembled' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'give speech at' is the wordplay.
I cannot quite see how this works, but
'speech' could be 'lecture' (synonyms) and 'lecture' is found within the answer.
'at' is present in the answer.
The remaining letters 'there' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for lecture theatre that I've seen is " hall".)
