Spooner's time aroused is expressed articulately (4,6)
I believe the answer is:
well spoken
'spooner's time aroused' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'expressed articulately' is the wordplay.
I cannot really see how this works, but
'expressed' could be 'spoken' ('spoken' can be similar in meaning to 'expressed') and 'spoken' is located in the answer.
The remaining letters 'well' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for well spoken that I've seen before include "Articulate" , "with cultivated accents" .)
