Prior To in a Sentence: Meaning and Grammar Examples
Prior to means before or earlier than a particular time or event. A prior to sentence such as “We checked the tickets prior to departure” places the checking first. Follow the phrase with a noun phrase or an -ing form; use before when you want a simpler or less formal alternative.
- Prior to means before.
- Prior to is more formal than before.
- A noun phrase can follow prior to.
- An -ing form can follow prior to when it names an activity.
- Before can also introduce a full clause.
What does prior to mean?
Prior to identifies a time earlier than a stated event or point. “Prior to the meeting” means before the meeting, not during it or after it. The phrase gives an order but does not specify how much earlier unless the sentence adds a time interval.
“She arrived prior to lunch” does not tell readers whether she arrived five minutes or two hours earlier. “She arrived ten minutes prior to lunch” supplies the interval. If timing is important, name the event and duration rather than relying on the formal phrase to create precision it does not contain.
How do you use prior to in a sentence?
Follow prior to with a noun phrase or an -ing form naming an activity. Put the phrase near the event it relates to so the sequence is clear. The following original examples show the pattern at the beginning and end of a sentence.
| Example sentence | Pattern |
|---|---|
| We checked the tickets prior to departure. | Prior to plus a noun. |
| Prior to the lesson, we arranged the chairs. | An opening time phrase. |
| Wash your hands prior to preparing the food. | Prior to plus an -ing form. |
| The team met two days prior to the match. | A stated interval. |
| She had practiced the piece prior to the audition. | One past event before another. |
| Read the instructions prior to assembly. | A formal instruction. |

Why does prior to take an -ing form?
In prior to, to belongs to a prepositional phrase rather than introducing an infinitive. When a verb-based activity follows, use its -ing form: “prior to leaving,” not “prior to leave.” A noun phrase is also possible: “prior to departure.”
Compare “We packed prior to leaving” with “We packed before we left.” The first uses an -ing activity; the second uses before with a full subject-verb clause. “Prior to we left” does not fit the ordinary pattern. If you want to identify the person performing the earlier action explicitly, the before clause can be clearer.
Prior to versus before
Prior to and before share the earlier-than meaning in these timing examples. Before is shorter and fits a wider range of structures because it can also be an adverb or conjunction. “We spoke before” is complete in an appropriate context; “We spoke prior to” normally needs a completion.
Choose prior to when a formal tone fits the document and the structure is clear. Choose before for a direct everyday instruction: “Read the label before using the product.” Neither choice automatically makes a statement more accurate. A style preference for before is different from a claim that prior to is grammatically wrong.
Where do commas belong?
A time phrase at the start often takes a comma to separate it from the main clause: “Prior to the lesson, we arranged the chairs.” At the end, a tightly connected timing phrase usually needs no comma: “We arranged the chairs prior to the lesson.”
With a short opening phrase, writers may omit the comma if the meaning remains clear. With a longer phrase, the comma makes the boundary easier to see: “Prior to the first rehearsal of the new term, the conductor checked the instruments.” Do not insert a comma between prior and to; they work together as a phrase.

Avoid unclear timing and incomplete comparisons
Keep the completion attached to the intended action. “We reviewed the notes prior to the test” clearly places the review first. “We reviewed prior notes” instead uses prior as an adjective describing earlier notes, so it has a different structure even though the words look related.
Do not let a timing statement imply a cause that has not been established. “The lights went out prior to the announcement” says only that one event happened earlier. For a useful prior to sentence, name both events and add a duration when necessary. Replace the phrase with before as a quick check that the timing still makes sense.
Practice writing your own sentence
- Choose a subject: a person, animal, object, or group.
- Decide whether the event is present, past, or connected to the present.
- Add the verb form and a meaningful completion.
- Read the sentence aloud and check what the verb describes.
Try changing one detail at a time. Replace the subject first, then the time expression, and check whether the verb must change. This keeps the meaning stable while making the grammatical difference visible. Compare your new sentence with the examples rather than copying a pattern whose meaning you do not understand.

Frequently asked questions
Does prior to mean immediately before?
No. Prior to means earlier than the stated event, but it does not specify a short interval. Add immediately, shortly, or an exact time if that distinction matters: “ten minutes prior to departure.” Without such wording, readers know the order but cannot infer how close the two events were.
Can I start a sentence with prior to?
Yes. “Prior to the concert, the musicians tuned their instruments” starts with a timing phrase followed by the main clause. The opening phrase supplies context for the action. A comma often helps mark the boundary, especially if the phrase is long, though short introductory phrases may appear without one.
Is prior to one word or two?
Write prior to as two words. The phrase works together to express before, but it is not normally joined or hyphenated in this use. “Prior-to departure” is not the standard construction. Prior can also appear separately as an adjective, as in “prior experience,” where it describes something earlier.
Can prior to refer to a future event?
Yes. “Please submit the form prior to the workshop” refers to an action that should occur before a future event. Prior to itself does not make the sentence past tense. The main verb and surrounding context determine whether the sentence describes a past action, present arrangement, or future requirement.
