Uproar when wearing gaudy jewellery that's very bright (8)
I believe the answer is:
blinding
'very bright' is the definition.
'blinding' can be an answer for 'bright' (similar in meaning). I am not sure about the 'very' bit.
'uproar when wearing gaudy jewellery' is the wordplay.
'uproar' becomes 'din' (both can mean a commotion or fuss).
'when wearing' means one lot of letters goes inside another (letters are worn by the letters containing them).
'gaudy jewellery' becomes 'bling' (informal term for jewellery. I am not sure about the 'gaudy' bit.).
'din' going into 'bling' is 'BLINDING'.
'that's' acts as a link.
Can you help me to learn more?
(Another definition for blinding that I've seen is " Rendering unable to see".)
