Translation guide
English uses -s/-es to mark plurals, but Japanese generally does not. Instead, plurality is inferred from context or indicated by quantity words, reduplication, or specific suffixes for people. This guide covers how to express plural concepts naturally in Japanese.
Japanese usually does not mark plurals; context or numbers indicate quantity.
The most common way to express plurality: simply use the noun without any suffix, letting context or quantity words clarify the number.
In Japanese, nouns do not change form for number. 'Cat' and 'cats' are both 猫 (ねこ). Use numbers or counters if you need to specify quantity.
There is a cat. / There are cats.
There are three cats.
When referring to groups of people, especially in polite or formal contexts, suffixes like たち, がた, or ら can be used.
Attached to a noun referring to a person (or sometimes an animal) to indicate a group including that person. Common and neutral/polite. 私たち (we), 子供たち (children).
Some nouns can be reduplicated to indicate plurality or a collective sense, often with a change in reading (rendaku). This is not productive for all nouns.
Japanese uses counters (助数詞) and quantity words to specify number, which inherently implies plurality when the number is more than one.
The standard way to specify a counted number of items. The counter depends on the noun's shape/type. Example: 三冊の本 (three books).
Adding たち or ら to inanimate objects or abstract nouns is usually incorrect. For example, 'books' is just 本, not 本たち. Use quantity words or context instead.
I read books.
たち is neutral and common for people (and sometimes animals). がた is honorific and used for respected groups. ら is informal or humble, often for pronouns. Avoid ら in polite conversation.
We are students.
The children are playing in the park.
Polite/honorific plural suffix for people. Used with titles or respectful terms: 先生がた (teachers), お客様がた (guests).
I am honored to meet the teachers.
Informal or humble plural suffix for people. Often used with pronouns: 彼ら (they, male or mixed), 我ら (we, humble). Can sound rough or literary.
They already went home.
Reduplication of 人 (ひと, person) meaning 'people' in general. Very common.
Listen to people's opinions.
Reduplication of 国 (くに, country) meaning 'various countries' or 'nations'. Note the rendaku (くに→ぐに).
I traveled to various countries in Asia.
Reduplication of 山 (やま, mountain) meaning 'mountains' (many mountains). Often used in literary or descriptive contexts.
The distant mountains are white with snow.
I bought two tickets.
Five friends are coming.
Means 'many' or 'a lot'. Can be used as an adverb or noun modifier. たくさんの人 (many people).
Many stars are visible.
Means 'some' or 'several'. Implies an unspecified plural number.
There are several problems.
