The spelling of the word "wert in to" may seem confusing, but it follows the rules of English phonetics. The word is actually a contraction of "were" and "not" and is commonly pronounced as "wərnət." In IPA phonetic transcription, this is represented as /wər nət/. The "e" in "were" is dropped and the "o" in "not" is pronounced as a schwa sound. This contraction is commonly used in casual speech and informal writing.
