Have with you the top brooches and hand jewellery (5)
I believe the answer is:
bring
'have' is the definition.
(I know that bring is a more specific form of have)
'top brooches and hand jewellery' is the wordplay.
'top' says to take the initial letters (in a down clue, the first letter is top).
'and' is a charade indicator (letters next to each other).
'hand jewellery' becomes 'ring' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The initial letter of 'brooches' is 'b'.
'b'+'ring'='BRING'
'with you the' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for bring that I've seen before include "Conduct" , "Convey" , "Fetch; cause to come" , "Carry (to a place)" , "Transport" .)
