In the Confusables series, we talk about English words and expressions that are easily confused with one another because of similarities in spelling, pronunciation, and/or meaning.
This is a source of confusion but it shouldn’t be, because the difference is clear-cut!
As usual, I am not going to provide a grammatical analysis. Instead, we’re just going to look at some typical sentences together.
Read the sentences carefully and make sure you understand them, then repeat them aloud a couple of times, play with them and try to make similar sentences (you can do this in the comments), and finally tuck them somewhere safe in your brain for future use. :-)
