Temperature that may be caught? (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 rest of the clue.
Can you help me to learn more?
(Other definitions for cold that I've seen before include "Nippy" , "Unfriendly" , "Glacial" , "Unemotional; infection" , "Lacking affection" .)
