A reader of one of my recent posts asked for an explanation of the difference between aught and ought. Aught is a very old-fashioned word, found mainly in old literature or poetry. Strangely, it can mean ‘anything’ or ‘nothing’, depending on the context. Ought is both a less common spelling of aught and (much more importantly) a very common modal verb, used in sentences such as: You ought to take more exercise.
In reality, most people go through their whole lives without ever using the word aught, so they are not likely to confuse the two. However, the question made me think about more common words that my students (and also many mother-tongue speakers) often muddle up.
