Short of Time vs. Short on Time – Which is Correct?
Both short of time and short on time are correct English phrases. Use short of time when emphasizing a limited amount or insufficient time; use short on time when emphasizing a person’s current lack of available time. In everyday speech, they are often interchangeable, but context can influence choice slightly.
Short of Time or Short on Time – Which is Correct?
Both phrases are valid in American English, and both mean that there is not enough time to complete something. The main difference is emphasis. Short of time commonly describes a situation in which the available time is insufficient, while short on time often describes a person, group, or schedule that currently has too little time available.
In many sentences, either phrase sounds natural. For example, “We are short of time” and “We are short on time” communicate essentially the same idea. However, short on can sound slightly more conversational and often highlights a temporary shortage.
Distinguishing these expressions also benefits from comparing them with “In Time” vs. “On Time”, which addresses a related timing distinction.
The Best Trick to Remember the Difference
Use the preposition that best matches the idea you want to emphasize. Think of short of as meaning “lacking an amount of something,” while short on means “having too little of something available right now.” If you could replace the phrase with not enough time remains, short of time is a natural choice. If you could replace it with we do not have much time available, short on time works especially well.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| short of time | Fixed prepositional phrase | Having insufficient time | We are short of time, so let us focus on the final question. |
| short on time | Fixed prepositional phrase | Having little time available | I am short on time today, but I can call tomorrow. |
How to Use Short of Time
Short of time means that the amount of time available is insufficient for a task, decision, journey, or activity. It is common in both casual and formal English. The phrase often appears with forms of be, such as am short of time, is short of time, and are short of time.
This phrase can focus on an approaching deadline or on the limited duration of an activity. It may sound slightly more neutral or formal than short on time, particularly in professional writing.
Example 1: We are short of time, so please keep your presentation brief.
Example 2: The rescue team was short of time before the storm reached the coastline.
Example 3: If you are short of time, read the introduction and conclusion first.
Etymology of the Phrase Short of Time
Short comes from the Old English word scort, meaning limited in length or extent. The preposition of developed from an Old English form expressing separation, source, or relation. Over time, short of became an established English pattern meaning “lacking” or “having less than needed,” including in the phrase short of time.
How to Use Short on Time
Short on time means that a person, group, or schedule has less time available than needed. It is especially common in everyday conversation and workplace communication. The phrase often presents time as a resource that someone currently possesses in limited supply.
Short on time can also sound more immediate and personal than short of time. A speaker might say, “I am short on time this morning,” to explain why they cannot stay, respond, or complete another task.
Example 1: I am short on time, so could we discuss this after lunch?
Example 2: The editor was short on time before the magazine went to print.
Example 3: We are short on time, but there is still enough time to check the figures.
Etymology of the Phrase Short on Time
The adjective short has long been used to describe a deficiency or shortage, as in being short of money or short of supplies. The preposition on developed through the broader expression short on something, meaning to have too little of it. The phrase short on time reflects this productive, conversational pattern.
