Off vs. Off of – Which is Correct?

Both “off” and “off of” are valid in American English, but “off” is usually the cleaner, more concise choice. Use “off of” when emphasizing movement away from a surface or in conversational speech. In formal writing, prefer “off,” although “off of” is not automatically incorrect or ungrammatical in every context.

Off of or Off – Which is Correct?

Off and off of are both valid expressions in American English. The single word off is generally preferred in formal, edited, and concise writing. The phrase off of is common in everyday American speech and can add emphasis to the idea of moving away from a surface, position, or person.

In most sentences, removing of does not change the meaning: “The cat jumped off of the table” and “The cat jumped off the table” mean the same thing. However, off the table sounds more polished and is preferred by many style guides and editors.

The Best Trick to Remember the Difference

Use the delete test: write the sentence with off of, then remove of. If the sentence still sounds natural, choose off in formal writing. For example, “She stepped off of the train” becomes the smoother “She stepped off the train.” Keep off of when its conversational tone or added emphasis is intentional.

Word	Part of Speech	Meaning	Example
off	Preposition or adverb	Away from, not on, or separated from something	Please take your shoes off the table.
off of	Prepositional phrase	Away from or down from something; usually conversational	The child climbed off of the chair.

How to Use Off

Off is a versatile preposition and adverb that indicates separation, movement away, removal, or a position that is not operating. It is the most concise choice in sentences describing movement away from a surface or location. It works well in casual, professional, academic, and formal writing.

As a preposition, off is followed by a noun or noun phrase: “The bird flew off the roof.” As an adverb, it can stand alone: “The alarm went off.” It also appears in many established expressions, including “off duty,” “off balance,” “off limits,” and “take off.”

Example 1: The books fell off the shelf during the earthquake.

Example 2: Please turn off the lights before you leave.

Example 3: The cyclist veered off the road to avoid the obstacle.

Etymology of the word off

Off comes from Old English of and related Germanic forms that expressed separation, distance, or movement away. Over time, it developed into the distinct modern word off, while of retained other meanings involving possession, connection, and association.

How to Use Off Of

Off of is a prepositional phrase used primarily in conversational American English. It describes movement away from a surface, object, position, or person. It is especially common after verbs such as jump, climb, fall, step, and take.

Although off of is widely understood and grammatically acceptable in many American contexts, some readers consider it wordy because off alone usually conveys the same meaning. For formal documents, business writing, academic work, and edited publications, off is normally the safer choice.

Example 1: The dog jumped off of the couch when the doorbell rang.

Example 2: She carefully lifted the vase off of the narrow ledge.

Example 3: The actor asked the crowd to move off of the stage.

Etymology of the phrase off of

Off of combines the older word off with the preposition of. The phrase became especially established in American English, where speakers often use an additional preposition to make the relationship between movement and a surface more explicit. It remains more common in speech than in formal edited prose.

Related Concepts

Understanding prepositions and register helps explain why both expressions work while one may be preferable in particular situations.

• Prepositions: Prepositions show relationships involving location, movement, time, or direction. In “The cup slid off the desk,” off connects the movement with the desk.
• Prepositional phrases: A prepositional phrase contains a preposition and its object. In “off of the platform,” off of functions together to describe movement away from the platform.
• Register: Register refers to the level of formality used in language. Off is neutral and suitable for nearly every setting, while off of has a more conversational American tone.
• Redundancy: Redundancy occurs when extra wording does not add necessary meaning. Some editors view of in off of as unnecessary, even though the full phrase is commonly used.

Examples from Media and Literature

Both forms appear in real-world communication, but their distribution often reflects the formality of the context.

• Movie dialogue: Characters in informal scenes may say, “Get off of me!” because the longer phrase adds emotional emphasis and sounds natural in spontaneous speech.
• News writing: A report is more likely to say that a passenger was removed “off the train” or that debris fell “off the roof,” reflecting a preference for concise wording.
• Children’s literature: A story may use “The kitten climbed off the bed” in narration but use “Get off of that chair!” in a character’s dialogue to convey a conversational voice.
• Historical fiction: Formal narration generally favors “The soldier stepped off the wagon,” while an informal character may say, “I just fell off of it.”
• Everyday advertising: Instructions such as “Keep food off the counter” typically omit of because short, direct wording is easier to read.
