eer, ere, ere (adv.), ere (prep., subord. conj.)
Both these words are pronounced like the word air. Eer, ere, and ere are archaic and poetic forms of the adverb ever, as in Where eer [ere, ere] she is, there would I be also; the apostrophe indicates the omission of the v. (This word is a versifiers delight: choose the two-syllabled ever or the more literary one-syllabled ere/ere/eer, as your meter requires.) Ere is an archaic or at least old-fashioned and poetic preposition and subordinating conjunction meaning before, as in the palindrome Able was I ere I saw Elba.
