An entanglement, we note (3)

I believe the answer is:

web

'an entanglement' is the definition.
(I know that entanglement can be written as web)

'we note' is the wordplay.
'note' becomes 'b' (musical note).
'we'+'b'='WEB'

(Other definitions for web that I've seen before include "Tangle" , "The worldwide one is a computer network" , "Spider's network" , "Insect trap" , "Internet site for spider?" .)

I've seen this clue in the Evening Standard.
