List non-exhaustive examples: 〜や〜など
Signal an open sample with the particle や (“things like A and B”), optionally capped with など (“et cetera”), in contrast to the exhaustive locked box と.
Non-Exhaustive Listing: 〜や〜など
tsukue no ue ni hon ya pen nado ga arimasu

The whole list or a few examples
Micro-Shiftりんごと バナナを 買いました。
Complete listI bought apples and bananas.
と gives the complete list: these two things, and nothing else.
Example Sentences
There are books, notes, and other things.
How it works
や introduces non-exhaustive items from a broader open group, while など seals the list with 'etc.'
I bought things like bread and milk.
Mental Model: The Open Picnic Basket vs The Locked Safe
Japanese provides two distinct tools for joining nouns in a list, each carrying an entirely different mental commitment:
- The Locked Safe (と): Exhaustive closure. When you link nouns with と, you lock the container. The listener assumes everything you bought, saw, or brought has been fully catalogued: リンゴと バナナを 買いました。 (“I bought apples and bananas—and strictly nothing else.”)
- The Open Picnic Basket (や): Non-exhaustive sampling. When you link nouns with や, you reach into an open basket and lift out two or three appetizing examples. The listener understands instinctively that many other unmentioned items remain inside: リンゴや バナナを 買いました。 (“I bought things like apples and bananas [among other groceries].”)
The Role of など: The Explicit “Et Cetera”
While や alone is already non-exhaustive, adding など at the end of the series makes the open-ended nature 100% explicit:
[Noun 1] や [Noun 2] など
- In the Room: 机の 上に 本や ペンなどが あります。 (“There are books, pens, and other such things on the desk.”)
- Shopping: スーパーで 野菜や 肉などを 買いました。 (“I bought vegetables, meat, and so forth at the supermarket.”)
Syntactic Rule: Particles Follow After など
A key grammatical detail often missed by learners: など behaves syntactically as a noun!
Therefore, when the list functions as a subject, direct object, or destination, the required grammatical particle (が, を, に, で) attaches directly after など:
- Direct Object (などを): パンや 牛乳などを 買いました。 (“Bought bread, milk, and so forth.”)
- Subject / Presence (などが): 京都や 奈良などに 古い 寺などが あります。 (“In places like Kyoto and Nara, there are old temples and such.”)
- Destination / Location (などに): 週末は カフェや 図書館などに 行きます。 (“On weekends I go to cafes, libraries, and similar places.”)
Solo など: Modesty and Categorization
など does not always require や! It can attach to a single noun to mean “things like [X]” or to convey humble modesty:
- Single Noun Example: 休日は 読書などを して 過ごします。 (“On days off, I spend time doing things like reading.”)
- Humble Self-Deprecation: 私などには 分かりません。 (“Someone insignificant like me wouldn't understand.”)
Common Pitfalls to Avoid
- Pitfall 1: Connecting verbs with や:
や connects nouns only. To list non-exhaustive actions (verbs), you must use the 〜たり〜たりする pattern:
Wrong:
*本を 読むや 映画を 見るCorrect: 本を 読んだり 映画を 見たり します。 - Pitfall 2: Trailing や:
Never put や after the final noun:
Wrong:
*本や ペンや などCorrect: 本や ペンなど - Pitfall 3: Mixing と and や:
Stick to one strategy throughout a list:
Wrong:
*本と ペンや ノートCorrect: 本や ペンや ノート
