Shatter in manifest cold (6)
I believe the answer is:
shiver
'shatter' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for shiver that I've seen before include "Momentary tremble" , "Slightly shake" , "Tremble slightly as from cold" , "Frisson" , "Tremble from cold or with fear" .)
