In an answer I wrote:
- sources of insomnia: improper food, some (yet) undetected illness / disease / affection, accumulated stress, some strong expectations about the (near) future, love, ...
and in exchange I received a comment:
"sources of insomnia: [..] affection" Hehe I think you meant affliction
Of course, I used "affection" with the meaning of "state of illness".
A search reveals that "affection" might be archaic, but not all sources share this information / belief.
On the other hand, I am not very familiar with "affliction", so I am hesitant to use it.
So my question (to native speakers) is: which one of them fits better? Which one is more common in every-day language? Of course, they might also be totally interchangeable, but I do not know.
