Come on is a phrasal verb with several everyday jobs: it urges someone to try harder, describes work that is progressing, and marks the moment a light or a show starts. In a sentence it stays fixed, so you write come on, never on come, and add to only for the flirtatious phrase come on to someone.
Come on at a glance
- Come on is a phrasal verb, not a single word, and the particle on never separates from come.
- It is intransitive, so it takes no direct object and cannot be made passive.
- Its main jobs are encouraging someone, urging speed, showing progress, and marking a light, machine or broadcast starting.
- The three-part phrase come on to someone means to flirt or make a sexual advance.

What does come on mean?
Come on is a phrasal verb meaning to make progress, to begin working or appearing, or, as an exclamation, to encourage or hurry someone. The Cambridge entry for come on groups the exclamation and the progress sense, and the split matters: one is a shout and the other is a description. Where a writer means plain physical movement, advance steadily carries the idea without a particle.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Encouragement | Urge someone to try harder | Come on, you can solve it. |
| Hurry | Tell someone to move faster | Come on, the bus leaves in a minute. |
| Progress | Advance or improve steadily | The repairs are coming on nicely. |
| Start operating | Begin to work or light up | The porch light came on at dusk. |
| Start broadcasting | Begin to be shown or aired | The quiz comes on after the news. |
| Disbelief | Say that something is hard to believe | Come on, nobody runs that fast. |
One limitation is worth stating. Come on is informal in most of its uses, so a report should not say the project came on well when it can say the project progressed. As a call to a person it can also sound impatient, so reach for it only when impatience is the intended tone.
How do you use come on in a sentence?
Come on stays in one piece because it is intransitive: the verb takes no object and the particle cannot move to the front or split away. To encourage someone, use it alone or with a name; to describe progress, add an adverb such as well; to place a broadcast, add at and a time.
| Pattern | Example | What it signals |
|---|---|---|
| come on (standalone) | Come on, keep going. | An imperative cheer; no object follows. |
| be coming on + adverb | The seedlings are coming on well. | Steady progress, common in British English. |
| subject + come on | The heating came on at six. | A machine or light starts working. |
| come on at + time | Her show comes on at eight. | A scheduled broadcast begins. |
| come on to + person | He came on to a colleague. | Flirtation; keep on and to joined to the person. |
Because nothing follows the verb, you cannot passivise it: there is no sentence like the light was come on. If you need an object, choose another verb, such as encourage someone or hurry someone along.
