Cut off vs. Cutoff – Which is Correct?

Both “cut off” and “cutoff” are correct, but they serve different grammatical roles. Use “cut off” as a verb or adjective phrase when describing separation, interruption, or exclusion. Use “cutoff” as a noun for a limit or deadline, or as an adjective modifying a related noun in standard English usage.

cut off or cutoff – Which is Correct?

“Cut off” and “cutoff” are both correct American English forms, but they are not interchangeable. The two-word form, cut off, is usually a phrasal verb or an adjective phrase. It describes stopping something, separating something, blocking access, or excluding someone.

The one-word form, cutoff, is usually a noun meaning a limit, endpoint, or deadline. It can also function as an adjective before a noun, as in cutoff date or cutoff point.

Word	Part of Speech	Meaning	Example
cut off	Phrasal verb or adjective phrase	To stop, separate, block, or exclude	The storm cut off power to the town.
cutoff	Noun or attributive adjective	A limit, deadline, endpoint, or related modifier	The application cutoff is Friday.

The Best Trick to Remember the Difference

Use the action-versus-limit test. If the sentence describes an action that stops, separates, or blocks something, write cut off as two words: “The call was cut off.” If the sentence refers to a limit, deadline, or endpoint, write cutoff as one word: “The income cutoff is $50,000.”

A useful visual mnemonic is this: “cut off” shows something being cut away, while “cutoff” names the line where something ends.

How to Use cut off

Cut off is a common phrasal verb. It can mean to separate one thing from another, interrupt a supply or communication, stop someone from speaking, prevent access, or exclude a person from a group or activity. It can also describe something that has been separated or interrupted.

As a phrasal verb, cut off may be transitive or intransitive. When it has an object that is a pronoun, the pronoun generally appears between cut and off: “The operator cut me off.” With a noun object, both positions can sometimes work: “She cut off the branch” or “She cut the branch off.”

Example 1: Heavy snow cut off several mountain communities.

Example 2: Please do not cut me off while I am explaining the problem.

Example 3: The technician cut off the damaged cable before replacing it.

What are the different forms of cut off?

The verb cut off contains the irregular verb cut. Its base form is cut off, its third-person singular present form is cuts off, and both its simple past and past participle forms are cut off. The -ing form is cutting off.

• Present: I cut off the water supply; she cuts off the water supply.
• Past: The accident cut off the highway.
• Past participle: The village has been cut off from the main road.
• Present participle: Workers are cutting off the old pipes.

When cut off is used as an adjective phrase, it does not change form: “a cut-off branch,” “a cut-off community,” and “cut-off communication.” In many contexts, especially before a noun, the hyphenated form cut-off may be used to show that the phrase functions as a single modifier.

Etymology of the word cut off

Cut comes from Middle English and is related to older Germanic words describing the action of dividing or slicing. The word off comes from Old English and expresses separation or distance. Together, cut off developed its literal meaning of separating by cutting and later acquired broader meanings involving interruption, exclusion, and disconnection.

How to Use cutoff

Cutoff is most often a noun. It refers to a point, number, level, or time beyond which something no longer applies or is no longer allowed. Common expressions include cutoff date, cutoff time, cutoff point, cutoff score, and age cutoff.

Cutoff can also act as an attributive adjective, meaning that it modifies a noun placed after it. In phrases such as cutoff date and cutoff score, it identifies the type of date or score being discussed.

Example 1: The registration cutoff is midnight on August 15.

Example 2: Applicants who score below the cutoff will not advance to the next round.

Example 3: The store announced an earlier holiday shipping cutoff.

What are the different forms of cutoff?

As a noun, cutoff usually forms its plural by adding -s: cutoffs. For example, “The program has different cutoffs for each age group.” As an adjective, cutoff does not change form: “cutoff dates,” “cutoff scores,” and “cutoff requirements.”

Do not confuse the noun cutoff with the verb phrase cut off. The verb changes according to tense and subject, while the noun generally remains cutoff or becomes cutoffs in the plural.

Etymology of the word cutoff

Cutoff developed from the phrase cut off. The noun originally referred to something separated or removed by cutting. Over time, it acquired the figurative meaning of a boundary or stopping point, which is now common in discussions of deadlines, eligibility, scores, prices, and measurements.
