What does spill over mean?
Spill over is a phrasal verb meaning to flow past a boundary, either literally as liquid or figuratively as an effect that reaches a new area. The Cambridge entry for spill over records both the liquid sense and the spreading sense, and the examples show how often the figurative use carries the meaning.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Overflow a container | Liquid passes the rim | The milk spilled over onto the table. |
| Spread beyond limits | An effect reaches a new area | The dispute spilled over into trade talks. |
| Fill and crowd out | People move past capacity | Fans spilled over into the car park. |
One limitation is worth stating. Spill over does not mean a slow leak, and it does not name the container. A tap that drips does not spill over; a full bath does. Where nothing crosses a boundary, contain the damage and hold are the more accurate verbs.
How do you use spill over in a sentence?
Because the verb is intransitive, the thing that overflows is the subject and never an object. The preposition then carries the whole direction of the movement, so into, onto and from each mark a different relationship.
| Pattern | Example | What it signals |
|---|---|---|
| subject + spill over | The bath spilled over. | Intransitive; the container overflows. |
| spill over + into | Anger spilled over into the next day. | Names the new place or time. |
| spill over + onto | The paint spilled over onto the floor. | Names the surface below. |
| spill over + from | Trouble spilled over from the coast. | Names where the overflow started. |
| spill over + to | Costs spilled over to consumers. | Shows who receives the effect. |
Where the image is a container filled to the top, brim with excitement describes fullness without any crossing, so it suits a scene that has not yet overflowed.

Spill over vs overflow
The two verbs look interchangeable until the sentence asks what crossed. Overflow stresses a container that can take no more, while spill over stresses the movement across a boundary. A glass can overflow without spilling anywhere, and a crowd can spill over without any container at all.
| Attribute | spill over | overflow |
|---|---|---|
| Core image | Movement past an edge | A container past its limit |
| Needs a boundary | Usually, named with into or onto | No, the limit is internal |
| Figurative use | Very common; effects and crowds | Also common; emotion and abundance |
| Typical subject | Water, anger, crowds, costs | River, bath, bin, feeling |
| Register | Neutral to journalistic | Neutral to literary |
Verdict: choose overflow when the container is the point, and spill over when the crossing into a new place or time is the point.

Frequently asked questions about spill over
Is spill over one word or two?
The phrasal verb is two words, spill over, as in the bath spilled over. The related noun is one word, spillover, and means a secondary effect, as in a spillover of the conflict. Keep the two spellings apart, because only the two-word form works as a verb.

What is a spillover effect?
A spillover effect is a consequence that spreads from one situation into another, often unexpectedly. A factory strike can have a spillover effect on deliveries in a different city. The noun keeps the same idea of crossing a boundary, but it names the result rather than the action itself.
Is spill over transitive or intransitive?
Spill over is intransitive, so it never takes a direct object. You say the water spilled over, not the child spilled over the water; in the second sentence the transitive verb spill is doing the work. Adding into or onto after the verb does not change this, because those are prepositions.
Spill over refers to the unintentional or unexpected spread or overflow of something, often from one area or situation to another. This term is commonly used to describe the transfer of effects or consequences beyond their original boundaries.
