Annoy a novice with something prickly (6)
I believe the answer is:
teasel
'something prickly' is the definition.
I can't tell whether this defines the answer.
'annoy a novice' is the wordplay.
'annoy' becomes 'tease' (I've seen this in another clue).
'a novice' becomes 'L' (as in a learner driver with L-plates on their car).
'tease'+'l'='TEASEL'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for teasel that I've seen before include "Plant with prickly flower heads" , "Plant with spiny purple flower heads" , "Eel sat up on the plant" , "Elates with nap-brushing device" , "Sat eel up on the herb" .)
