EP25: Forget to do vs Forget doing

Hello hello, fellow learners of English, how are you doing out there? This is Kristian here, nice to be with you again, and welcome to the Learners of English Podcast, episode number 25.

In this episode I’d like to start something new. We’re going to talk about easily confused words and phrases in English. For this new series, each episode will be under two minutes. My goal is not only to teach you something useful each workday, but also to help you make learning English a habit in your daily life.

OK, let’s get the ball rolling. Today we’re going to look at the difference between forget to do and forget doing. So the first one is forget + infinitive and the second one is forget + -ing verb.

Listen carefully to these two examples:

  • I forgot to write the email to my colleague
  • I forgot writing the email to my colleague

Notice the difference in the way that I said these examples. When we use the word forget + the infinitive with to, it means you were supposed to do something but you didn’t actually do it. So I was supposed to write the email, but I didn’t.

However, when we use the word forget followed by an -ing verb, it means that you did do something, but you have no memory of it, you don’t remember doing it. So I did write the email, but I don’t recall it.

Got it?

All right, don’t forget to subscribe to the Learners of English podcast on your favorite podcast app.
