Excitable, somewhat touchy perhaps (5)
I believe the answer is:
hyper
'excitable' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'somewhat touchy perhaps' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'HYPER' can be found hidden inside 'touchy perhaps'.
Can you help me to learn more?
(Other definitions for hyper that I've seen before include "Unusually energetic" , "Overexcited" , "publicist" , "Prefix meaning excessively, perhaps active" , "Slang adjective for over-active or highly-strung" .)
