Silver band not in prominent position, causing difficulties (5)
I believe the answer is:
aggro
'difficulties' is the definition.
(I've seen this before)
'silver band not in prominent position' is the wordplay.
I cannot really see how this works, but
'silver' could be 'ag' (Ag is the chemical symbol for silver) and 'ag' is found in the answer.
'band' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'causing' is the link.
Can you help me to learn more?
(Other definitions for aggro that I've seen before include "offensive behaviour" , "Violence - difficulties" , "Bovver!" , "belligerent troublemaking" , "Hostile troublemaking" .)
