Shakespearean fairy (6)
I believe the answer is:
cobweb
'shakespearean fairy' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cobweb that I've seen before include "fairy, in part" , "Gossamer - A Midsummer Night's Dream fairy" , "Spun trap" , "Gossamer trap" , "Spun threads" .)
