Suffer with cold and perish? I've ripped coats (6)
I believe the answer is:
shiver
'suffer with cold' is the definition.
(shivering is a reaction to cold temperatures)
'perish? i've ripped coats' is the wordplay.
'coats' says the answer is hidden in the clue (I've seen 'coat' mean this (I've seen this in other clues)).
'SHIVER' is hidden in the letters of 'perish ive ripped'.
'and' is the link.
(Other definitions for shiver that I've seen before include "Shudder" , "Frisson" , "Smash; tremble" , "Tremble slightly as from cold" , "Shake with cold or fear" .)
