Let's say, in a question on this site, I am giving you two sentences which I think probably carry the same meaning and I want to ask you if I can use either of them interchangeably. I feel like if I say,
- "Can I use either of them"
- "Are/Is either of them okay",
it could be understood that I am asking if any of the two sentences I gave can be used while I am trying to ask if both of the sentences can be used. Do you think I can use the word, "either," in these questions, or do I have to use the word, "both," as in
- "Can I use both of them"
- "Are both of them usable"?
