Even native English speakers have difficulty remembering the correct pronunciation and spelling of certain words that are easily confused due to their similarities in sound or appearance. Most of the time, people know which word they mean, and because the confusable words are often homophones, such errors won’t be noticed in spoken conversation. In written correspondence, though, these errors will jump out at a reader. Take some time to study these word pairs, and make sure you’re letter-perfect on the spelling as well as confident in using them in context.
