Went to ground – somehow Kane's missing a lot after vacation (5)
I believe the answer is:
knelt
'went' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe there's a link between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for knelt that I've seen before include "Assumed posture of prayer" , "Genuflected" , "Prepared to pray?" , "Got down (to propose)" , "Bent the knee" .)
