Built on arrangement of beads (5)
I believe the answer is:
based
'built' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'arrangement of beads' is the wordplay.
'arrangement of' is an anagram indicator.
'beads' is an anagram of 'BASED'.
'on' is the link.
Can you help me to learn more?
(Other definitions for based that I've seen before include "foundation" , "Worthless" , "Located" , "Stationed (in a place)" , "Founded, grounded" .)
