Material from entry-level crossword (6)
I believe the answer is:
velcro
'material' is the definition.
(I know that Velcro is a type of material)
'from entry-level crossword' is the wordplay.
'from' says the answer is hidden in the clue.
'VELCRO' is hidden within 'entry level crossword'.
(Other definitions for velcro that I've seen before include "It fastens" , "Fastening tape" , "Modern cloth fastener with two strips pressed together" , "Fastener with tiny hooked threads" , "In clover with cloth fastener" .)
