Question about 'coldness'

[learning54]

Right, but then winter would appear twice in the same sentence.

In winter, my grandmother wears a heavy jacket to protect herself from the cold.
My grandmother wears a heavy jacket to protect herself from the winter cold.
(NOT "coldness")

Both cold and coldness are nouns and their use depends upon context.
An immediate coldness swept through the house once the heating was turned off.
I have a cold.

Hi John,
Thank you so much for your reply.
I think that the sentence is too complicated for the students.
Could you please, give me one where ''cold/coldness' may be choosen, but with a crystal clear difference between them?

Thanks in advance
