Pineapple angered new worker for starters (4,7)
I believe the answer is:
hand grenade
'pineapple' is the definition.
(pineapple can informally mean a grenade)
'angered new worker for starters' is the wordplay.
I cannot quite see how this works, but
an anagram of 'angered' is 'grenade' which is present in the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is found within the answer.
The remaining letters 'had' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hand grenade that I've seen before include "Tree with edible nuts" , "Manually launched explosive device" , "Small explosive device for throwing" , "Explosive device that is thrown" , "Small thrown bomb" .)
