Key Takeaways

Definition of ‘This Matter’

You may have heard the phrase ‘this matter’ used in conversations or in text, but what does it mean?

This matter refers to a particular topic or issue that is being discussed. It is often used as a blanket term for the subject at hand, allowing the speaker to refer back to it without having to explain further.

For example, if two people are discussing cleaning up after a party, one might say, “On this matter, I think we both agree that we should split the work evenly”. In this case, ‘this matter’ refers to the discussion of who should do what tasks related to cleaning up after a party.

In another context, someone could say, “In this matter I cannot make any promises”. Here ‘this matter’ would be referring to whatever specific thing was just mentioned that has made them hesitant about making any promises.

Overall, ‘this matter’ can be used as an umbrella term when discussing a particular topic or issue and allows for easier conversation flow without having to constantly restate what is being discussed.

On This Matter Vs. in This Matter

Comparing ‘on this matter’ and ‘in this matter’, there is a slight distinction.

On this matter implies an action or opinion related to the subject, while in this matter suggests the subject itself.

For example, if you said ‘I have an opinion on this matter’ then you are suggesting that you have something to say about the topic.

Whereas if you said ‘I have experience in this matter’ then it implies that you have some first-hand knowledge of what’s being discussed.

In essence, using ‘on’ indicates your stance regarding the issue at hand; whereas using ‘in’ emphasizes your familiarity with it.

Examples of ‘On This Matter’

You’re likely familiar with the phrase ‘on this matter’, but here are some examples of how it’s commonly used:

‘I’m confident on this issue,’ ‘I’m not sure on that decision,’ and ‘Let’s discuss it further on this point.’

This phrase is often used to refer to a specific problem, situation, or idea. For instance, if you were discussing an upcoming election, you might say something like, ‘We should research the candidates more on this matter.’

It can also be used when making a decision. For example, if someone was deciding whether to take a job offer or not they might say something like, ‘I need to think more on this matter before I decide.’

In any case, the phrase highlights an important subject that needs further discussion or deliberation.

Examples of ‘In This Matter’

Considering ‘in this matter’ typically refers to a specific issue, it’s often used when making decisions or discussing important topics.

For example, when someone needs to make a tough choice they’ll say something like ‘I’m still undecided in this matter.’

Additionally, business leaders will use it when discussing an issue that requires careful consideration, such as ‘Let’s take some time and think through all aspects of this matter.’

Lastly, people may also use it during heated debates to emphasize the importance of the subject: ‘We need to be sure we’re looking at all angles in this matter’.

Summary of ‘On This Matter’ and ‘In This Matter’

You’ll often come across the phrases ‘on this matter’ and ‘in this matter’ when discussing important topics or making decisions.

‘On this matter’ is used to refer to a subject that can be discussed with some degree of certainty, whereas ‘in this matter’ refers to something that is still in dispute or needs further consideration.

For example, if a person were considering whether or not to invest in a certain business venture, they might say ‘I’m still undecided on this matter,’ implying that there is more information needed before making a decision.

Alternatively, if they had already done their research and decided to move forward with the venture, they could say ‘I am confident in this matter.’

In both cases, the speaker is referring to the same issue; however, the context clues help determine which phrase should be used.
