なり / たり: The Classical Copula | Japanese Grammar

The modern copula — だ, です, である — feels like a small, worn-down word, and it is. Its ancestor is the classical copula, and there were two of them: なり and たり. Both are contractions of a location particle plus the verb あり（"to exist"）: なり＝ に＋あり, たり＝ と＋あり. That etymology is the whole insight of this page. Because だ, である, and even the attributive な of な-adjectives all descend from this same に／にて＋あり family, learning なり and たり is not learning an exotic form — it is meeting the full-length copula that everyday Japanese shrank from. Once you see the family resemblance, 祝詞（のりと, Shinto prayers）, legal contracts, and 時代劇（じだいげき, period drama）dialogue stop looking like a foreign dialect.

One family: に／にて＋あり

Every modern way of saying "X is Y" traces back to a noun plus a form of あり. Lay the family out and the relationships snap into focus.

Source	Contracts to	Lives on today as
に＋あり	なり	断定なり; the attributive な (静かなる → 静かな)
にて＋あり	であり → である	である → だ; the て-form で (静かで)
と＋あり	たり	たり copula; the elevated 〜たる (堂々たる)

💡

The single most demystifying fact about the copula: だ is not a "basic word" with である as a fancy variant. It is the other way round. である ← にてあり, and だ is である worn down further. なり is である's classical sibling on the very same に＋あり path. You are not learning a relic; you are learning the original of the word you use every day.

And the attributive な that you already know from な-adjectives（静かな部屋）is literally なり's attributive form なる, eroded: 静かなる → 静かな. So な-adjectives are, historically, nouns plus the classical copula. Keep that in mind — it is why the pieces below will feel oddly familiar.

なり: the 断定 copula

断定（だんてい） means "assertion / definite statement" — the copula's core job, "X is Y." 断定なり attaches to a 体言（noun）or a 連体形, and it conjugates on the ラ変（ra-hen）pattern:

未然形	連用形	終止形	連体形	已然形	命令形
なら	なり／に	なり	なる	なれ	なれ

春なり。

haru nari

It is spring. (体言春 + 終止形なり — the plainest classical 'X is')

これは天下の名品なり。

kore wa tenka no meihin nari

This is a masterpiece without equal. (断定なり asserting identity, the ancestor of これは名品だ)

The 未然形なら gives the negative ならず（なら＋ず, "is not"）and the conditional ならば — you already meet ならば in the modern conditional なら:

真実ならず。

shinjitsu narazu

It is not true. (なら + classical negative ず — an inscription-style flat denial)

And the copula participates in 係り結び（かかりむすび）, the classical concord where a focus particle forces a special sentence-ending form. After こそ, the copula ends in its 已然形なれ — a pattern preserved verbatim in period-drama self-declarations:

我こそは真田幸村なれ。

ware koso wa Sanada Yukimura nare

I am none other than Sanada Yukimura! (こそ forces the 已然形なれ — the classic 時代劇 name-declaration)

The other なり: 伝聞・推定

Here is the trap that catches even advanced learners. There is a second なり, homophonous but unrelated: the 伝聞・推定（でんぶん・すいてい, hearsay / inference） auxiliary, meaning "I hear that…" or "it sounds like…". You tell them apart by what they attach to:

断定なり (に＋あり): attaches to a 体言 / 連体形 — 春なり, 名品なる.
伝聞・推定なり (from an auditory root): attaches to the 終止形 — 春来（く）なり "spring is said to be coming."

The famous opening of the 土佐日記（とさにっき）turns on exactly this:

男もすなる日記といふものを。

otoko mo su naru nikki to iu mono o

The diary that men are said to keep… (す is 終止形 + 伝聞なる — 'are said to' — not the copula)

If なり follows a noun, it is the copula ("is"). If it follows a plain terminal verb, suspect the hearsay auxiliary ("is said to"). Same three syllables, opposite meaning.

たり: the elevated copula

たり＝ と＋あり, and it too conjugates on the ラ変 pattern:

未然形	連用形	終止形	連体形	已然形	命令形
たら	たり／と	たり	たる	たれ	たれ

This copula たり came into Japanese with kanbun and carries a stiff, formal ring — which is why its attributive たる survives today on adjective-like descriptors of dignity and rank. Do not confuse it with the other たり, the perfect/aspectual auxiliary たり（て＋あり） that attaches to a 連用形（見たり "have seen"）. The copula たり attaches to a 体言（noun）:

堂々たる態度で会見に臨んだ。

dōdō taru taido de kaiken ni nozonda

He faced the press with a dignified bearing. (堂々 + copula たり's 連体形たる)

確固たる証拠がない。

kakko taru shōko ga nai

There is no firm evidence. (確固たる — 'solid, unshakeable' — the same たる)

The 未然形たら survives in the weighty 〜たる者（もの）frame — "one who is a …, in one's capacity as a …" — a staple of editorials and speeches:

会長たる者、模範を示すべきだ。

kaichō taru mono, mohan o shimesu beki da

One who is chairman ought to set an example. (たる者 = 'in one's role as' — たり alive in formal rhetoric)

主たる原因は資金不足であった。

shu taru gen'in wa shikin busoku de atta

The main cause was a shortage of funds. (主たる = 'principal' — a fossilized たる descriptor)

Where they survive today

You do not need to read 古文 to meet なり and たり. They are lodged in ordinary modern Japanese:

自分なりに精一杯やった。

jibun nari ni seiippai yatta

I did my very best in my own way. (自分なり — the fossilized 断定なり, still fully productive: 私なり, 彼なり, それなり)

それなりの覚悟が必要だ。

sore nari no kakugo ga hitsuyō da

It calls for a fitting degree of resolve. (それなり = 'of its own kind/degree', 断定なり)

事実は小説より奇なり。

jijitsu wa shōsetsu yori ki nari

Truth is stranger than fiction. (a set saying that keeps 断定なり — 奇 'strange' + なり)

それは単なる偶然ではない。

sore wa tan naru gūzen de wa nai

That is no mere coincidence. (単なる = 単 + なる, the 連体形 of 断定なり — an everyday word built on the classical copula)

And である itself is the same family, one branch over — the written-register copula you will meet in essays and reports, descended from にてあり exactly as なり descended from にあり:

人間は考える葦である。

ningen wa kangaeru ashi de aru

Man is a thinking reed. (である ← にてあり, なり's sibling; see the written copula である)

Read those five examples again: 自分なりに and 単なる are things you say without a second thought, yet each is the classical copula in disguise. That is the payoff — なり and たり are not exotic; they are the full-length である/だ that daily speech filed down.

Common mistakes

❌ 桜が咲くなり、春だ。

sakura ga saku nari, haru da

Wrong parse — reading a 終止形 + なり as the copula 'is'. After a plain verb, なり is hearsay ('is said to bloom'), not 'X is Y'.

✅ 春なり。／桜咲くなり（＝咲くそうだ）。

haru nari / sakura saku nari

'It is spring' (copula, after a noun) vs. 'the cherries are said to bloom' (hearsay, after a verb). The attachment tells you which.

断定なり follows a noun; 伝聞・推定なり follows a terminal verb. Ignore the attachment and you invert the meaning.

❌ 堂々たり態度

dōdō tari taido

Wrong — using the 終止形たり to modify a noun. To modify a noun you need the 連体形.

✅ 堂々たる態度

dōdō taru taido

a dignified bearing (before a noun, the copula takes its 連体形たる, never 終止たり)

English speakers reach for the "dictionary form" たり everywhere. But modifying a noun demands the attributive たる — just as なり becomes なる before a noun.

❌ 会長たる者は模範を示すべく、たる者の責任がある。

Wrong — treating たる者 as a fixed noun and doubling it. たる is a live copula form (会長 + たり), not a suffix meaning 'person'.

✅ 会長たる者、模範を示すべきだ。

kaichō taru mono, mohan o shimesu beki da

One who is chairman should set an example. (たる者 = 'one who IS a …'; the noun slot before たる is what changes)

たる者 is copula + 者 ("one who is X"), not an unanalyzable word. Swap the noun（社長たる者, 親たる者）and it keeps working.

❌ 単なだけの偶然。

tan na dake no gūzen

Wrong — treating 単なる like a normal な-adjective and clipping it to 単な. It is frozen as 単なる.

✅ 単なる偶然。

tan naru gūzen

a mere coincidence (単なる keeps the full 連体形なる; there is no 単な)

Because 単なる is a fossil of the classical copula, it does not behave like a modern な-adjective — the なる cannot shrink to な here.

Key takeaways

The classical copula came in two: なり＝に＋あり and たり＝と＋あり, both "noun + あり" contractions.
だ, である, and the attributive な all descend from this に／にて＋あり family — なり is である's classical sibling, not an unrelated relic.
断定なり conjugates なら／なり・に／なり／なる／なれ／なれ; watch for the homophonous 伝聞・推定なり that attaches to a 終止形 and means "is said to."
The copula たり conjugates たら／たり・と／たり／たる／たれ／たれ; its 連体形たる survives in 堂々たる, 確固たる, 主たる, and the 〜たる者 frame.
Everyday survivals: 自分なりに, それなり, 単なる, 事実は小説より奇なり（なり）and 堂々たる, 会長たる者（たり）— proof that the classical copula is hiding in plain modern sight.
