Endless quest organised at home for sparkly thing (6)
I believe the answer is:
sequin
'sparkly thing' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'endless quest organised at home' is the wordplay.
'endless' means to remove the last letter.
'organised' is an anagram indicator.
'at home' becomes 'in' (similar in meaning).
'quest' with its final letter removed is 'ques'.
'ques' with letters rearranged gives 'sequ'.
'sequ'+'in'='SEQUIN'
'for' is the link.
Can you help me to learn more?
(Other definitions for sequin that I've seen before include "Spangle used to decorate clothing" , "that sparkles" , "Sparkling feature of ballroom dancing?" , "small ornamental circle" , "Small circular spangle for ornamenting clothing" .)
