Notion Meaning: The Word, the Sewing Term and the Notion App

“Notion” means an idea, belief or general understanding of something, often one that is vague, partial or not fully thought through, as in “I have a rough notion of how it works.” It can also mean a whim or sudden inclination, and in American English the plural “notions” refers to small sewing supplies; many people searching the word today, though, are trying to figure out what the productivity app Notion is.

This guide covers all three, so you can tell which “notion” someone means.

The dictionary meaning of “notion”

Dictionaries agree on a core sense with a few branches. Dictionary.com gives the main meaning as a general, often imperfect understanding of something, and also lists “an opinion, view or belief.”

The senses you will meet most often:

1. A vague or general idea. “She had only a hazy notion of what the job involved.”
2. An opinion or belief. “He rejected the notion that remote teams can’t ship fast.”
3. A concept (formal use). In philosophy or academic writing, “the notion of fairness” simply means the concept of fairness.
4. A whim or impulse. “On a sudden notion, we drove to the coast.” Older and more literary, but still common.
5. Notions (plural, mostly US): small sewing articles. More on this below.

Common phrases

• “Have no notion of” means to have no idea or understanding of something.
• “Take a notion to” means to suddenly decide to do something.
• “Notional”, the adjective, means existing as an idea rather than in reality. In finance it shows up in “notional value”, meaning a nominal or face amount rather than money actually changing hands.

Notion vs. idea vs. concept

In practice they often swap freely. Reach for “notion” when you want to suggest the idea is fuzzy or held without much evidence.

Where the word comes from

According to Etymonline, “notion” entered English in the late 14th century (spelled nocioun) from Latin notionem, a form of notio. That Latin word is built on noscere, “to come to know,” which traces back to the Proto-Indo-European root gno-, “to know.” It is related to words like “know,” “notice” and “cognition.”

Etymonline also notes that Cicero coined the Latin notio as a translation of Greek philosophical terms such as ennoia, “act of thinking, conception.” The meaning later loosened:

• “An opinion, a view, a somewhat vague belief” dates from about 1600.
• “A not very rational inclination, a whim” is recorded by 1746.

That drift explains why the word can sound either scholarly or slightly dismissive depending on context.

What “notions” means in a fabric or craft store

If you saw “Notions” on an aisle sign, it has nothing to do with ideas. In American English, notions are the small items used in sewing: things attached to a finished garment, such as buttons, snaps, zippers and hooks and eyes, plus small tools like needles, pins, thread and seam rippers. Fabric stores typically group these into a notions section.

In British English the same category is usually called haberdashery. Confusingly, in the US a “haberdasher” traditionally sells men’s clothing and accessories, so the two terms don’t map perfectly across regions.

What “Notion” means as an app

On a site about work tools, this is the sense most readers are after. Notion is a workspace app for notes, documents, task tracking, wikis and databases, made by Notion Labs, Inc., based in San Francisco. It runs in a web browser and as apps for desktop and mobile.

A short background

Most sources, including the Wikipedia article summarized on Wikiwand, say the company was founded in 2013, with Ivan Zhao and Simon Last named most often as founders. Some sources list additional co-founders, so accounts differ slightly. The product launched publicly in 2016, first for web and Mac, with Notion 2.0 and an Android app following later. User counts vary by source and date; French tech outlet Siècle Digital reported in September 2024 that Notion had reached 100 million users.

We could not find an official statement from Notion explaining why the product carries this name. It’s the ordinary English word for an idea, which suits a tool for capturing thoughts, but any specific naming story should be treated as unconfirmed.

The building blocks: blocks, pages and databases

When people say “put it in Notion,” they’re usually talking about three concepts:

• Blocks. Notion’s help center explains that every piece of content is a block: a paragraph, heading, image, to-do item or list. A page is a stack of blocks, and you can turn one block type into another or drag it to a new spot.
• Pages. A page is itself a block, so you can nest pages inside pages to build a hierarchy, such as a team wiki with sub-pages per project.
• Databases. Per Notion’s help center, a database is a collection of pages. Each row is a full page with properties you can filter and sort, and the same data can be shown as a table, board, list, calendar or gallery.

Notion also includes AI features. Its help docs describe options to edit a block with AI or ask the AI a question from the block menu. Feature names, plan limits and pricing change often, so check Notion’s own site for current details as of November 2026.

“Notion” as everyday jargon

Because the app is widely used, you’ll hear it used almost like a verb or a place: “It’s in Notion,” “Notion it,” or “check the Notion page.” In those cases people mean the shared workspace, not an idea. Context usually makes it obvious: a capital N and talk of pages, docs or databases means the app.

How to tell which “notion” someone means

1. Capital letter and work context? Almost certainly the Notion app.
2. “The notion that…” or “a notion of…”? The ordinary word: an idea or belief.
3. Plural, in a shop or sewing pattern? Sewing notions like thread, zippers and buttons.
4. “Took a notion to…”? A whim or sudden decision.

Bottom line

As a word, “notion” means an idea or belief, often a loose one, and it comes from the Latin for “to know.” As a plural in a craft store, it means small sewing supplies. As a proper noun, it’s a widely used workspace app built around blocks, pages and databases. Dictionary senses are stable. App details such as features, plans and user numbers change, so treat those as accurate as of November 2026 and confirm on Notion’s official site before deciding anything.
