The や Particle: Non-Exhaustive Listing "And"
The や particle is a non-exhaustive listing "and." It connects two or more nouns and presents them as representative examples of a larger, open set.12 Where と names a complete list, や signals that the speaker is naming only a few items and leaving room for others.13
Overview
What や marks in one line
The pattern "A や B (や C)" reads as "A and B (and C), among others." The listed nouns are samples from a broader category. The "and others" meaning is built into the particle itself rather than added by a separate word.143
Reference grammars classify や as a 並列助詞 (heiretsu-joshi, parallel-listing particle), in the same family as と, とか, やら, だの, and か. Each particle handles "listing" differently, including contrasts such as open vs closed and neutral vs casual.25
パンや牛乳を買いました。6
"I bought bread and milk (among other things)."
JLPT level and where textbooks introduce it
や is a JLPT N5 (beginner) grammar point.7 Genki I introduces N1 や N2 in Lesson 11, alongside the conventional ~など closer.8 Minna no Nihongo I introduces や in Lesson 10 as part of the early listing toolkit and contrasts it directly with と.6
Register snapshot
や is formal-to-neutral in tone. It lives comfortably in essays, news prose, menus, and careful spoken Japanese.910
In casual conversation, the same job often shifts to とか, which is colloquial and structurally more flexible than や.95
Form and rules
Position: between nouns only
や sits between each listed noun in the pattern N1 や N2 (や N3 …).12 It attaches to nouns and to nominalised expressions, meaning expressions made noun-like with の.2 In this parallel-listing use, や is medial only: it never appears at the start or end of a sentence.5
One critical point separates や from the rest of its family: unlike とか and だの, や is not attached to the final listed noun.5
Write パンや牛乳, not パンや牛乳や. とか and だの may close the list with a final copy of the particle, but や cannot.5
赤や黒や青が混ざり合っている。2
"Red, black, blue, and other colours are mixed together."
The conventional や〜など closing
The textbook-default frame is N1 や N2 (や N3) など. The closer など means "and the like" or "etc." and makes the open-list reading explicit.83 Genki and Minna no Nihongo treat the pairing as a fixed teaching pattern rather than an optional flourish.86
Bare "A や B" already implies "and others." など simply reinforces that implication when the writer wants to leave no ambiguity.93
りんごやバナナなどが好きです。8
"I like fruit such as apples and bananas."
What や cannot list
や lists nouns and noun phrases only. It does not connect verbs, verb phrases, adjectives in predicate position, or full clauses.1711
For verbs and verb phrases, the standard replacements are ~たり~たりする (neutral) or ~とか~とか (casual).1211 Learners who have just met や often overgeneralise it into those slots.711
✗ 読むや書くやしたい。
The natural form uses ~たり~たりする instead:
読んだり書いたりしたい。11
"I want to do things like read and write."
Stacking with case particles
A case particle (が, を, に, で, and so on) attaches once, after the last listed noun, not after each や-linked item.15 For case marking, the や-list behaves as one noun phrase.
東京や大阪に行きました。8
"I went to Tokyo and Osaka (among other places)."
コンビニでお水やおかしを買った。7
"I bought things like water and snacks at the convenience store."
Nuance and usage contexts
The implicit "etc."
A bare "A や B" already encodes "A, B, and other members of the same category." The "and others" reading is carried by the particle itself, not contributed by など.13
など promotes that built-in implication to an explicit closer.93 When precision matters, such as in formal writing, instructions, or contractual prose, spelling out "etc." with など is the safer choice. In flowing speech, leaving it implicit is fine.
Exemplification (例示) vs enumeration
や performs exemplification (reishi, 例示): the listed items are presented as representative samples of a category, not as the full membership of that category.53
The exemplification reading is natural with menu items, room contents, weekend plans, languages spoken, and places visited.8710
部屋に本やゲームがあります。9
"There are books, games, and other things in the room."
昼ごはんにはサンドイッチやサラダを食べます。8
"For lunch I eat things like sandwiches and salads."
Speaker stance
Choosing や over と is a deliberate stance about list completeness, not just a stylistic choice. や signals "I am naming a few; the list is bigger than this."14 と, by contrast, commits to "these and only these."13
Writing and formal speech vs casual speech
や is at home in essays, news prose, and polite spoken Japanese.910 In casual conversation, the same listing function often shifts to とか. It is colloquial and accepts a wider range of categories on either side.9511
Contrasts with nearby particles
や vs と: open list vs closed list
The biggest N5 confusion around や is the contrast with と. と marks a closed, exhaustive list: the listed items are the complete set. や marks an open, non-exhaustive list: the listed items are examples of a larger set.13 The exhaustive uses of と are covered in "The と Particle: With, And, Quote".
学生と先生が来ました。3
"The student and the teacher came." (only those two)
学生や先生が来ました。3
"Students, teachers, and others came." (more people present)
や vs とか: register and what each can list
Both や and とか are non-exhaustive listers.1012 They differ in two ways: register, and what categories they accept on either side.
| Axis | や | とか |
|---|---|---|
| Register | Formal / neutral | Casual |
| Connects nouns | Yes | Yes |
| Connects verbs / verb phrases / clauses | No | Yes |
| Repeats on the final item | No (✗ N1 や N2 や) | Yes (N1 とか N2 とか) |
週末は買い物や映画に行きます。3
"On weekends I do things like shopping and going to the movies."
週末は買い物するとか映画見るとかします。12
"On weekends I do things like go shopping or watch a movie." (casual)
や vs など: list-internal connector vs list-final closer
や and など are complementary, not competing. や goes between items, and など goes after the last item. The canonical pattern N1 や N2 など combines them.863
A bare …など (without や) can attach to a single item, as in 漫画など ("manga and the like"), as a stand-alone "etc." marker. や cannot stand alone in that way.513
Good to know
Reaching for や to connect verbs
The most common early-stage mistake with や is treating it as a general-purpose "and" and using it with verbs. や is a noun-only parallel particle, so verb listing belongs to ~たり~たりする (neutral) or ~とか~とか (casual).711 The natural form is:
読んだり書いたりしたい。11
"I want to do things like read and write."
Attaching や to the final listed noun
A second common slip is copying the とか pattern onto や and repeating the particle after the last item. や is medial only. The case particle (を, が, に, で, and so on) attaches once, after the final noun.15 The correct form is:
パンや牛乳を買いました。6
"I bought bread and milk (among other things)."
The dismissive shading of …など after a person or personal possession
や〜など is neutral in object lists. But など on its own, attached to a person or to the speaker's own actions (お前など, 私など, そんなものなど), can carry a belittling or self-deprecating tone similar to colloquial ~なんか.13 The pattern is not off-limits, but learners should hear the shift in register before using it with animate referents.
と as a fence, や as a trailing comma
A practical way to choose between the two listing particles on the fly: と "fences in" exactly the listed items, while や resembles a comma trailing off into "…", showing the open continuation.3
や as a 並助詞 sits in a paradigm of parallel particles
Reference grammars treat と, や, とか, やら, だの, か, and に as one functional family of 並列助詞 (parallel-listing particles). Each handles "listing" along axes such as closed vs open, neutral vs casual, and what categories of word it accepts.25 Seeing the paradigm at once clears up much of the confusion that appears when N5 listing expands into N4 and N3 grammar.
