One being strung along? (4)
I believe the answer is:
bead
'one being strung along?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bead that I've seen before include "Necklace element" , "Part of a necklace" , "Small drop of moisture" , "Necklace piece; droplet" , "Small ball with a hole through the middle" .)
