What does trail behind mean?
Trail behind means to move or remain at the back of a group, or to be less advanced than a rival or a standard. The Cambridge entry for trail behind records the physical sense of following at a distance, and the same frame carries into business and sport, where a company or a team trails behind the leaders. The word behind is fixed inside the phrase, so it cannot be swapped for a synonym, and the emphasis stays on relative position. A walker who falls back slowly may straggle in, but the group as a whole trails behind.
| Sense | Plain meaning | Example sentence |
|---|---|---|
| Stay at the back | Move behind the rest of a group | The youngest child trailed behind the others. |
| Be less advanced | Fall short of a standard or rival | The firm trails behind its rivals in sales. |
| Follow at a distance | Move slowly after someone | The dog trailed behind us all the way home. |
One limitation matters. Trail behind describes position or progress, not intent, so it does not say the subject is tired or unwilling. That is why it suits teams, prices and scores as readily as walkers. Where you mean a deliberately slow pace, dawdle or linger says more about the choice.
How do you use trail behind in a sentence?
Trail behind is intransitive, so it needs no object, and the group or standard being followed usually appears after behind as a prepositional phrase. The phrase inflects on trail, never on behind. When the gap is measurable, as in points or sales, writers often prefer lag behind, which points to a number rather than a position.
| Pattern | Example | What it signals |
|---|---|---|
| subject + trail behind | The team trailed behind for most of the match. | States position with no group named. |
| trail behind + the + noun | One runner trailed behind the pack. | Behind acts as a preposition taking the pack. |
| trail behind + in + area | The brand trails behind in online sales. | Names the field where progress is short. |
| be trailing behind | They are trailing behind by two goals. | Progressive form with a measured margin. |
| trailing behind + noun | A line of cars trailed behind the bus. | Participle describing a following group. |
Because trail behind is a fixed phrase, nothing may be inserted between the two words. You can say the runner trailed far behind, with far as an adverb before behind, but never the runner trailed the pack behind, because that turns an intransitive phrase into something it is not.

Trail Behind vs lag behind
Trail behind and lag behind look like twins and are used differently. Trail behind usually describes physical position or broad progress, while lag behind stresses a measured shortfall and often takes a figure. Where a rival pulls away quickly, the leader may get behind the schedule rather than the field.
| Attribute | trail behind | lag behind |
|---|---|---|
| Core meaning | Stay at the back or be less advanced | Fall short by a measurable amount |
| Typical subject | Walkers, teams, brands | Figures, wages, production |
| Commonest frame | trail behind the group | lag behind by ten percent |
| What it stresses | Relative position | Size of the gap |
| Register | Neutral and descriptive | Analytical and often numeric |
Verdict: choose trail behind when position or broad progress is the point, and lag behind when you can attach a number or a rate. The opposite direction is to outpace the field, which names the margin rather than the place.

The bottom line
Use trail behind in a sentence to say that a person, team or company is at the back or less advanced than the rest, and let the group or standard follow behind. The two details that decide most sentences are that the phrase is intransitive and fixed, so nothing splits it or reorders behind, and that it reports position rather than intent. When a measurable gap or a rate is the point, lag behind is the sharper partner.
Frequently asked questions about trail behind
Is trail behind one word or two?
Trail behind is always two words when it is used as a verb phrase, as in the team trailed behind. It is not a single-word verb, so it never appears as trailbehind in standard writing. The two words keep a fixed order, and only trail changes its ending for tense.
Does trail behind need an object?
Trail behind is intransitive in the sense that it needs no object, but it very often takes a phrase beginning with behind, such as trail behind the group or trail behind the leaders. That noun belongs to behind, not to trail, which is why the phrase can also stand completely alone, as in the team is trailing behind.
What is the difference between trail behind and lag behind?
Trail behind describes relative position or broad progress, so it suits walkers, teams and brands. Lag behind stresses a measurable shortfall and usually takes a figure, as in lag behind by ten percent. Both can describe a losing position, but only lag behind points to the size of the gap.
Can trail behind describe a company?
Yes. Companies, brands and economies all trail behind rivals when they are less advanced in sales, technology or growth. In this business sense the phrase usually names the field, as in trail behind in online sales, so the reader knows where the shortfall lies. It remains neutral about the cause.
