Daughter at store held up jeans (5)
I believe the answer is:
denim
'daughter at store held up jeans' is the definition.
I can't judge whether this defines the answer.
'daughter at store held up' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'at' says to put letters next to each other.
'store' becomes 'mine' (mine can mean a supply or store of something).
'held up' shows that the letters should be reversed in order.
'mine' backwards is 'enim'.
'd'+'enim'='DENIM'
Can you help me to learn more?
(Other definitions for denim that I've seen before include "Hard-wearing blue fabric" , "Fabric used for jeans" , "Durable material" , "Cotton twill fabric" , "maker of jeans" .)
