Come across non-professional sort of training? (3,5,2)
I believe the answer is:
lay hands on
'come across' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their base form.
Perhaps you can see an association between them that I can't see?
'non-professional sort of training?' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is present in the answer.
'non-professional' could be 'lay' (as in a layman) and 'lay' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lay hands on that I've seen before include "Move to confirm" , "Find" , "how one may heal by faith?" , "attack" .)
