Gets support from, when one intimidates (5,2)
I believe the answer is:
leans on
'gets support from' is the definition.
(I've seen this in another clue)
'when one intimidates' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is located in the answer.
'one' could be 'an' (an apple is one apple) and 'an' is found in the answer.
The remaining letters 'les' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for leans on that I've seen is " A Nelson (anag.)".)
