Throws away supports (6)
I believe the answer is:
slings
This clue might be a double definition.
'throws away' is the first definition.
'slings' can be an answer for 'throws' (I've seen this in another clue). I'm unsure of the 'away' bit.
'supports' is the second definition.
(sling is a kind of support)
Can you help me to learn more?
(Other definitions for slings that I've seen before include "Looped bandages for limb support or missile throwers" , "'''... to suffer the ... and arrows of outrageous fortune'' (Hamlet) (6)'" , "Catapults or arm supports" , "Arm bandages; drinks" , "Supporters" .)
