Commonly Confused & Misused English Words


Untitled Design

Are any words more frequently mixed up than there, their and they’re? They certainly are the first to come to mind for me. English is full of words that sound the same, but have totally differently spellings and meanings, as well as words that are spelled the same, but have totally different pronunciations and meanings. Ugh!

Even for native English speakers, choosing the correct word can be challenging. I have 8 years of university under my belt, using high level, formal English. Despite this, I still find myself questioning whether I’m using the correct word or not! Now imagine how difficult it might be if English isn’t your native language. It’s up to us English teachers to help make these tricky word decisions a little bit easier.
