THAN: Which one is which? Just one little letter, but it completely changes the meaning. One relates to time and sequence and the other is used to compare. Autocorrect on your phone won’t help you get this right – in fact it might trick you into making a mistake, so it’s up to you to know the correct word to use. In this lesson I’ll clarify the difference between these two important words, and give you a short test to help you practise using them. And of course there’s a quiz too, so do give it a try and test out your knowledge!
