A touch crazy, like Hazel perhaps (5)
I believe the answer is:
nutty
'a touch crazy' is the definition.
'nutty' can be an answer for 'crazy' (I've seen this before). I am not certain of the 'a touch' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for nutty that I've seen before include "Crunchy" , "Out to lunch" , "Mentally unhinged (slang)" , "Like brazils, say" , "like vegetarian roast?" .)
