Shook with cold three times as much around start of March (8)
I believe the answer is:
trembled
'shook' is the definition.
(trembling is a kind of shaking)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for trembled that I've seen before include "Shook from fear or cold" , "shivered" , "Shook involuntarily" .)
