Discussion On vs. Discussion About vs. Discussion Of – Difference Revealed

The different prepositions you can use after “discussion” have a very subtle difference in the overall meaning of the word. In this article, we’ll look at using “discussion on,” “discussion about,” and “discussion of” and what the differences are.

Should You Use “Discussion On,” “Discussion About,” Or “Discussion Of”?

“Discussion on” should be used when one person is doing most of the talking about a topic. “Discussion about” should be used when you want to talk about a topic but don’t have to stay on topic. “Discussion of” should be used when you want to stick to the topic.

Should You Use "Discussion On," "Discussion About," Or "Discussion Of"?

The difference is very slight, and most people use them somewhat interchangeably. You’ll often find that most native speakers won’t pay much attention to the differences between the three phrases, but it’s good to know which one means what.

Is “Discussion On,” “Discussion About,” Or “Discussion Of” Used The Most?

It will help you to understand them slightly clearer if we look at which one of the three is used the most.

In this graph, we can see that “discussion of” is by far the most popular choice, while “discussion on” and “discussion about” are roughly equal. “Discussion of” has been the favored phrase for at least the last 200 years.

Is "Discussion On," "Discussion About," Or "Discussion Of" Used The Most?

Generally, “discussion of” is the most popular choice because it allows us to stay more strictly on topic. Usually, when we host a discussion, the intention is to keep everything within the confines of the topic – making “discussion of” the best choice.

Sometimes, you might find yourself losing interest in the topic or moving on to another one. In these cases, you’ll use “discussion about,” though it’s much rare to come across.

Finally, in other cases, one particular person might be leading the discussion. If this is the case, then you’re having a “discussion on” something because someone is in charge of discussing that topic with you.

We believe that examples are some of the easiest ways for us to explain what we’re talking about. We’ll show you examples for each of the phrases and prepositions, and you can choose which ones work best for you after seeing it.

7 Examples Of How To Use “Discussion About” In A Sentence

Now let’s see how we might use “discussion about” in a different way. This is the most general preposition of the three and changes the meaning of “discussion” to represent that.

“Discussion about” is used when you want to talk about the topic in question but don’t mind if things get off-topic.

  1. Let’s have a discussion about how we’ll tackle this project.
  2. I want to have a discussion about my career.
  3. We should have a discussion about our relationship.

  7. Are you just going to turn down my idea without any discussion about it?

As you can see from these examples, we generally aren’t as specific with the topic. We don’t mention something specifically and instead come up with a general concept. This allows other ideas to float around during the discussion, which is primarily what the preposition “about” is used for.

Which Other Prepositions Can Be Used After “Discussion”?

There aren’t many other choices when it comes to using prepositions after “discussion.” The most important ones have already been covered, although we would like to discuss one more.

“Discussion with” is the only other preposition you’re likely to come across. We use it when we want to talk about the people who participated in the discussion or if we want to have a discussion with a particular person or group.

  • I’ll have a discussion with the committee.
  • We should set up a discussion with Dan from HR.
  • Let’s have a discussion with our partners.

Is It Correct To Say “Discuss On”?

Finally, we wanted to quickly talk about the phrase “discuss on.”

“Discuss on” is grammatically incorrect when we want to use the verb “discuss” to talk about something specifically. We never use any prepositions after the verb “discuss” because it does enough to clarify our intended meaning.

  • We should discuss the details.
  • We should discuss on the details.

As you can see, the first example is correct, and “on” is an error that we shouldn’t use when “discuss” is in the verb form.
