State of agitation associated with a close shave (6)
I believe the answer is:
lather
'state of agitation' is the definition.
(as in the phrase 'in a lather')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for lather that I've seen before include "Panic" , "Frothy bubbles from soap" , "Agitated state" , "Froth formed by soap and liquid" , "Soapsuds" .)
