“Not to mention” introduces an additional related fact that the writer or speaker wants to emphasize. It often adds a point that makes the first statement seem stronger: “The apartment is close to work, not to mention surprisingly quiet.” The phrase can introduce a noun phrase, a gerund phrase, or a clause, as long as the new information has a clear relationship to the main idea.

What Does “Not to Mention” Mean?
Cambridge Dictionary defines the idiom as a way to emphasize something being added to a list. In everyday use, it is close to as well as that, and another thing, or to say nothing of, but it can give the added point extra weight. For example, “The trail is scenic, not to mention well marked” presents the clear markings as an additional benefit.
The expression does not usually mean that the speaker will literally avoid mentioning something. It signals the opposite: a detail is being brought up because it strengthens, rounds out, or sometimes complicates the point just made. The tone can be conversational and emphatic, so use it when that emphasis is intended.
How to Use “Not to Mention” in a Sentence
The phrase can connect different kinds of grammatical material. A useful editing check is to identify what comes immediately before and after it, then make sure the relationship reads smoothly.
- Before a noun or noun phrase: “The museum has an excellent collection, not to mention a welcoming café.”
- Before a gerund phrase: “She likes the job for its flexibility, not to mention working with a thoughtful team.”
- Before a clause: “The delay is frustrating, not to mention that the replacement parts are expensive.”
- At the beginning for rhetorical emphasis: “Not to mention, the venue is accessible by train.” In more formal writing, connect this point to a complete sentence or recast it: “The venue is also accessible by train.”

Punctuation With “Not to Mention”
When the phrase adds a detail at the end of a sentence, a comma often comes before it: “The studio is bright, not to mention quiet.” Do not automatically add a comma between the phrase and the words it introduces. When the phrase is a parenthetical interruption, use a pair of commas: “The plan, not to mention its cost, was rejected.”
At the start of a sentence, writers often put a comma after an introductory “Not to mention”: “Not to mention, the schedule changed twice.” This standalone opening is common in informal writing, but it can sound like an incomplete afterthought in formal prose. To make the relationship explicit, attach the idea to a complete clause: “The schedule changed twice, and the venue was difficult to reach.” Purdue OWL’s guidance on commas after introductory elements explains that punctuation depends on the construction, not on a fixed rule for every opening phrase.
When “not to mention” interrupts a sentence as a parenthetical aside, use a pair of commas if removing it leaves a complete sentence: “The proposal, not to mention the revised budget, is ready for review.” Do not let commas separate a subject from its verb or otherwise obscure which words belong together.

Keep the Added Information Parallel
“Not to mention” works best when the added material matches the sentence around it. Parallel items are easier to read: “The course is demanding, not to mention rewarding” pairs two adjectives; “The role involves planning, not to mention coordinating events” pairs two -ing forms. If the parts do not fit, recast the sentence rather than forcing the phrase to carry an awkward connection.
For instance, “She is a skilled editor, not to mention she meets every deadline” mixes an adjective phrase with a full clause. It is understandable, but “She is a skilled editor, not to mention a reliable deadline keeper” makes the list parallel. Another clean option is to write two coordinated clauses: “She is a skilled editor, and she meets every deadline.”
“Not to Mention” vs. Similar Phrases
- Besides: Adds another reason or item and can sound conversational: “Besides the low price, the laptop has a long warranty.”
- As well as: Adds information in a more neutral way: “The fee covers meals as well as transportation.”
- To say nothing of: Similar in meaning, often with a more formal or literary feel: “The renovation will take months, to say nothing of its cost.”
- Let alone: Commonly follows a negative or limiting statement and introduces something even less likely: “They could barely afford the deposit, let alone the monthly rent.” It is not a general substitute for every positive use of “not to mention.”
Choose the phrase that conveys your intended logic. “Not to mention” usually adds emphasis; “besides” can add a separate reason; and “let alone” commonly makes a negative comparison more extreme.

When to Use It—and When to Revise
Use “not to mention” when the second point is relevant and gives the reader a reason to notice the first point more strongly. It can add a benefit, drawback, qualification, or practical detail. The connection should be obvious from the sentence or surrounding context.
Revise the phrase if it introduces a point unrelated to the main statement, repeats information, or creates a sentence fragment that distracts from your meaning. In academic or business writing, a direct connector such as also, in addition, or and may sound more neutral. In conversation, reviews, and persuasive writing, “not to mention” can give the added detail a natural emphasis.
Frequently Asked Questions
Is “not to mention” formal?
It is widely understood and acceptable in many kinds of writing, but it often sounds conversational or emphatic. For a neutral formal tone, use “in addition,” “as well as,” or a direct coordinated sentence when that better expresses the relationship.
Should there always be a comma after “not to mention”?
No. Punctuation depends on how the phrase fits into the sentence. A comma may follow it at the beginning of an emphatic afterthought, or set off a parenthetical aside, but a sentence such as “The trip was memorable, not to mention affordable” does not need a comma between the phrase and the adjective.
Can “not to mention” begin a sentence?
Yes, especially in conversational or rhetorical writing: “Not to mention, the tickets sold out in an hour.” For formal prose, consider connecting the point to the previous sentence or rewriting it as a complete, direct statement.
What is a synonym for “not to mention”?
Depending on the sentence, try “as well as,” “in addition to,” “to say nothing of,” or “besides.” “Let alone” fits a different pattern: it generally follows a negative or limiting statement and introduces something even more difficult or unlikely.
Can “not to mention” introduce a complete clause?
It can be followed by a clause, often with that: “The change is costly, not to mention that it delays the launch.” A noun phrase or a parallel phrase may sound more concise; choose the pattern that makes the relationship clearest.
