What about if a person feels cold and I am talking about him and I say "he feels cold again" ? Thank you!

He feels cold.

Li frèt.

or

Li santi l frèt.

He feels cold again.

Li frèt ankò.

or

Li santi l frèt ankò.

If the coldness is due to physiological changes because of impending death, then you'll say:

He feels cold.

He's cold.

Kò li frèt.
