Spontaneous Ringoe is ready to meet you (9)
I believe the answer is:
impromptu
'spontaneous' is the definition.
(I've seen this before)
'ringoe is ready to meet you' is the wordplay.
I cannot quite see how this works, but
'ready' could be 'prompt' (similar in meaning) and 'prompt' is found in the answer.
'you' could be 'u' (commonly used in online communication) and 'u' is found in the answer.
The remaining letters 'im' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for impromptu that I've seen before include "On the spur of the moment" , "Without pre-planning" , "Ad hoc: spontaneous-sounding musical piece mastered by Schubert" , "Extemporaneous speech" , "Unplanned; instrumental piece" .)
