Figure a snake can grab you! (5)
I believe the answer is:
clasp
'grab you' is the definition.
'clasp' can be an answer for 'grab' (thesaurus). I'm not sure about the 'you' bit.
'figure a snake' is the wordplay.
'figure' becomes 'cl' (I can't explain this - if you can you should give a lot more credence to this answer).
'a snake' becomes 'asp' (asp is a kind of snake).
'cl'+'asp'='CLASP'
'can' acts as a link.
Can you help me to learn more?
(Other definitions for clasp that I've seen before include "Bar on a medal ribbon" , "Clutch" , "Fastening - firm grip" , "Jewellery fastener" , "Grasp firmly" .)
