Hutchinson's feature? (4)
I believe the answer is:
chin
'feature?' is the definition.
(facial feature)
'hutchinson's' is the wordplay.
'CHIN' is hidden in amongst the letters.
However, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for chin that I've seen before include "What's repeatedly required for a toast" , "part of mug" , "Lower face part" , "Inch (anag.)" , "Part of the face (on which one may have to take it?)" .)
