Dispose of vs. Dispose off – Which is Correct?
The correct expression is “dispose of,” not “dispose off.” Use dispose of when you mean to get rid of, sell, discard, or deal with something. “Dispose off” is a common grammatical error caused by confusing the particle in this fixed phrasal verb with the preposition “of” in everyday writing.
Dispose of or Dispose off – Which is Correct?
Dispose of is the correct standard English expression. It means to get rid of something, throw something away, sell or transfer something, or deal with a matter. Dispose off is generally considered a misspelling or grammatical error in standard English.
The confusion usually comes from pronunciation. In connected speech, the words dispose of may sound similar to “dispose off,” especially because the final sound of dispose runs into the following unstressed word. However, the established expression always uses the preposition of.
The Best Trick to Remember the Difference
Use the replacement test: substitute get rid of for the phrase. If the sentence makes sense with get rid of, the correct expression is dispose of. For example, “We must dispose of the old equipment” means “We must get rid of the old equipment.” Remember: both expressions end with the same word, of.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| dispose of | Phrasal verb | To get rid of, sell, discard, or deal with something | Please dispose of the packaging responsibly. |
| dispose off | Incorrect phrase | Nonstandard form caused by confusion with “dispose of” | Do not write “dispose off the waste.” |
How to Use Dispose of
Dispose of is a transitive phrasal verb, so it normally takes a direct object. The object may be a physical item, such as waste or equipment, or an abstract matter, such as a problem, claim, or obligation. The phrase is grammatically correct in both American and British English.
In everyday conversation, throw away or get rid of may sound more natural when referring to ordinary household objects. Dispose of is especially common in formal, professional, technical, legal, environmental, and instructional writing.
Example 1: Residents should dispose of household batteries at an approved recycling center.
Example 2: The committee must dispose of the complaint before moving to the next case.
Example 3: She decided to dispose of the unused furniture before moving to a smaller apartment.
Etymology of the Word Dispose
Dispose comes from the Latin verb disponere, meaning “to arrange” or “to distribute.” It entered English through Old French. Over time, dispose of developed the meaning “to deal with” or “to get rid of,” while the standalone verb dispose can still suggest arranging or determining how something should be used.
