Hull's Hotel for my group on weekend is small (5)
I believe the answer is:
husks
'hull's hotel for my group' is the definition.
I can't tell whether this defines the answer.
'on weekend is small' is the wordplay.
'on' is an insertion indicator (as in clothing \'on\' a person).
'weekend' becomes 'k' (I've seen this in other clues).
'is small' becomes 'huss' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'k' put into 'huss' is 'HUSKS'.
Can you help me to learn more?
(Another definition for husks that I've seen is " Coverings, shells".)
