Wants to go right into hollow places (6)
I believe the answer is:
craves
'wants' is the definition.
(craving is a kind of wanting)
'go right into hollow places' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
'hollow' could be 'cave' (caving is a kind of hollowing) and 'cave' is found within the remaining letters.
A single letter 's' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for craves that I've seen before include "Feels a powerful desire" , "Hungers or longs for" .)
