Note insect by tip of canary grass (7)
I believe the answer is:
timothy
'grass' is the definition.
(I've seen this before)
'note insect by tip of canary' is the wordplay.
'note' becomes 'ti' (musical note, as in do re mi so fa la ti do).
'insect by' becomes 'moth' (I am not sure about this - if you are sure you should believe this answer much more).
'tip of' indicates one should take the final letters.
The last letter of 'canary' is 'y'.
'ti'+'moth'+'y'='TIMOTHY'
Can you help me to learn more?
(Other definitions for timothy that I've seen before include "young Cratchit at length?" , "Biblical writer" , "New Testament book" , "Companion to St.Paul; type of grass" , "A grass; an NT disciple" .)
