Entanglements from speed (5)
I believe the answer is:
knots
I believe this clue is a double definition.
'entanglements' is the first definition.
(I've seen this in another clue)
'speed' is the second definition.
(thesaurus)
'from' is the link.
(Other definitions for knots that I've seen before include "the going rate, in the main" , "They secure" , "Looped fastenings" , "Grannies, reeff etc" , "Tangles" .)
