An explanation of the different meanings of the English phrasal verb 'keep on' from a native speaker, with lots of examples in context
Hello and welcome to my website for English learners all about phrasal verbs where I explain their different meanings to help you understand, learn and use them like a native.
The phrasal verb 'keep on' is a great phrasal verb to know and use in order to make your English sound more native as it is used a lot in informal, spoken English. Unlike some other phrasal verbs, there is one general theme that runs through all of the meanings of 'keep on', which is the idea of continuation. We explore all of these meanings in this post, including uses that are particular to British English, as well as a number of different idioms that it features in. So, without further ado, let's get started....

THE BASICS
KEEP ON: KEY INFORMATION
Usage | Common |
Number of meanings | 5 |
Past tense forms | Kept on / Kept on |
Separable? | Sometimes |
Before we look at the individual meanings of the phrasal verb 'keep on', let's take a minute to examine the meanings of the individual words 'keep' and 'on'.
The main verb that we are interested in for this post is the verb 'to keep', which has two key meanings in English; the first is the idea of possession and the second is the idea of continuation. As previously mentioned, the idea of continuation is the theme behind all of the meanings of 'keep on' and this is that one that we will revisit again in this post.
In addition to 'keep', we have the prepositional particle 'on', which has a huge number of applications in English, however the application that we are interested in for this post is when it is used an adverb to indicate the continuation of something.
So, now that we have covered the basics, let's take a look at the meanings of the phrasal verb 'keep on'....
MEANING 1: To continue to do something
CEFR Language Level | B1 - Intermediate |
Usage | Common |
Where is it used? | Everywhere |
Potential synonyms | To continue, to keep, to carry on, to persist |
Separable? | No |
After reading the first part of this post, it should come as no surprise to you that the first meaning of 'keep on' is 'to continue to do something', or 'to repeatedly do something again and again'.
For this usage, we are simply combining the 'continuation' meaning of the verb 'to keep' with the 'continuation' meaning of 'on', giving us a double continuation. This usage of 'keep on' can often therefore be used as a synonym for 'keep', however whilst 'keep' can be used to talk about a continuation or a repetition of both active and stative verbs*, 'keep on' tends to be used more for active verbs only e.g. eating, talking, asking etc.
Normally, 'keep on' is used to by native speakers to talk about an action that they or someone else continues to do, without any positive or negative connotations. Sometimes though, it can be used to describe a repeated action that we find annoying or irritating. Alternatively, it can also be used to encourage people to continue what they are doing.
Grammatically, 'keep on' is always followed by the 'ing / gerund form of another verb, unlike 'to continue' which can be followed by either an infinitive or a gerund.
My business is doing really well, so I am just going to keep on running it in the same way for the moment.
He keeps on asking me to go out on a date with him and he won't take 'no' for an answer.
My neighbours keep on playing their music really loudly late at night and it keeps on waking me up!
The bullies will keep on bullying you until you fight back.
Don't give up, keep on working at it and success will be yours!
*Stative verbs are verbs which state a condition or a state and not an activity. Typical examples would be to believe, to belong, to love etc.
MEANING 2: To talk about something persistently
CEFR Language Level | B2 - Upper intermediate |
​Usage | Common |
Where is it used? | British English |
Potential synonyms | To go on, to harp on, to witter on, to bang on |
Separable? | No |
For our second meaning of 'keep on', we are staying with the theme of 'continuation and repetition' as this meaning is 'to talk persistently or excessively about something'.
This application of 'keep on' is, again, used to express annoyance, irritation or boredom about the way that somebody talks a lot, or persistently, about a particular subject. Normally, for this application we require the additional preposition 'about' to specify the subject in question that the person always talks about.
If you have read my post about the phrasal verb 'go on' (link here), you may remember that one of its meanings was very similar to this and it can therefore often be used as a synonym of 'keep on'. The only difference is perhaps that we can use 'go on' for someone who talks a lot in general and also about a specific topic, whereas 'keep on' tends to only be used when there is a specific subject. If you really want to get native speaker points, you could also combine the two and say that 'someone keeps going on about...'.
My parents went to see a show last week and now they constantly keep on about it, saying it was the best show that they have ever seen.
The interviewer was trying to get the actor to talk about his new film but instead he just kept on about the latest political developments.
In the run-up to the election, the winning party kept on about how it was going to make lots of changes to improve the economy but we have not seen any yet.
MEANING 3: To continue to wear something
​CEFR Language Level | B1 - Intermediate |
Usage | Average |
Where is it used? | Everywhere |
Potential synonyms | To continue to wear |
Separable? | Yes |
Our third meaning of 'keep on' is 'to continue to wear something', such as clothes, a hat, glasses or even a wig (more to follow on this in the upcoming Bonus section).
For this usage, we are taking the adverbial meaning of 'on' where it is used to mean 'to wear something' and combining with the continuation meaning of 'keep'.
This particular application is used in situations where you have the choice to remove an item of clothing or something that you are wearing and you decide not to remove it. In other words, you 'keep it on'.
This application of 'keep on' is separable and is normally used separably with the item of clothing going between 'keep' and 'on'.
It was so cold in the house that I kept my coat and gloves on when I went inside.
John kept his glasses on to go swimming and regretted it when they fell off and sank to the bottom of the pool.
Are we allowed to keep our shoes on or do we need to take them off before we enter?
IDIOM ALERT: Keep your wig on!
This particular application of 'keep on' has given rise to a common idiom in English, which has several variations.
'Keep your wig on' and its alternative forms 'keep your hair on' and 'keep your shirt on' is an expression in English that is used to tell someone to calm down and not be so angry about something. I would certainly exercise caution when using this as if it used in the wrong situation, it could make the person even angrier and the situation even worse.
Oh keep your wig on, Karen, it's really not that important!
Will you please tell John to keep his shirt on and to stop overreacting!
MEANING 4: To continue to employ someone
CEFR Language Level | C1 - Advanced |
Usage | Medium |
Where is it used? | Everywhere |
Potential synonyms | To retain |
Separable? | Yes |
The fourth meaning of 'keep on' is one that is used often in business English and that is 'to continue to employ someone'.
This is normally heard when an employee reaches the end of a probationary or trial period after starting within a company and the company then makes a decision as to whether or not they wish to keep the employee on their books or not.
Grammatically, this application of 'keep on' is separable and takes a direct object, with the employer being the subject and the employee being the direct object. It tends to be used much more in a separable way by native speakers, with the name of the person or the personal pronoun going between 'keep' and 'on'.
Another way that this application of 'keep on' is used is with rental contracts and agreements for houses and apartments. Here, a person can choose to 'keep on' a contract and continue to rent the house or property in which they live. In contrast to the employee example, the person renting is usually the subject and the contract or house is the direct object.
I thought that my company was going to dismiss me after my trial period had ended, but to my sheer amazement they kept me on!
A management decision was taken yesterday that due to the increasing costs that the company is facing, we will not be keeping any of the new employees on when their temporary contracts expire.
We have decided to keep the apartment on for another 3 months.
MEANING 5: To nag someone
CEFR Language Level | C1 - Advanced |
Usage | Medium |
Where is it used? | Everywhere |
Potential synoynms | To go on at, to nag, to pester |
Separable? | No |
The fifth and final meaning of 'keep on' requires the additional preposition 'at' and means to nag or pester someone. In other words, to continuously and persistently moan at someone about something or ask them to do something that they do not want to do. Again, this is a synonym of the phrasal verb 'go on at'. This usage is primarily a British usage but would certainly be understood elsewhere.
As mentioned above, the additional preposition 'at' is required here for the person who is the victim of this negative activity. In addition, the extra prepositions 'about' and 'to' can be used here to specify the reason for the nagging or the nagger's desired result.
My mother keeps going on at me about how untidy my room is but I don't think it is!
Roger's wife is always going on at him to finish painting the bedroom.
The teacher is always going on at her students about how they are dressed.

To keep on the straight and narrow = This idiomatic expression means to behave in an honest and lawful way, without getting into trouble.
