Temperature one can catch (4)
I believe the answer is:
cold
'temperature' is the definition.
(I know that cold is a type of temperature)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for cold that I've seen before include "Chilly; minor ailment" , "Lacking affection" , "made of stone" , "Lacking warmth" , "Biting" .)
