びる (biru) – Meaning | JLPT N1 Grammar

びる / びて / びた means to seem to be; to appear; to behave as ~. It is a JLPT N1 Japanese grammar pattern used to describe how something or someone looks, feels, or comes across — but only with a small, closed set of words that carry a worn, mature, or rustic nuance.

This grammar point often appears in descriptive writing, literary passages, and JLPT N1 reading sections. If you want to capture that subtle impression of age, maturity, or countryside charm without turning into a full-blown adverb or adjective, びる and its conjugations give you exactly the right tool.

びる is not a suffix you can attach to any adjective; it clings to a small, expressive set of words that capture a certain worn, mature, or rustic feel.

What does びる / びて / びた mean?

Use びる / びて / びた when you want to express that something or someone has the appearance or quality of ~, but without suggesting deliberate pretense. The feeling is more “it looks that way naturally” than “it’s trying to look that way.”

Natural translations include:

to seem to be; to appear; to behave as ~
(when modifying a noun) ～ような、～らしく見える(みえる)

The pattern is used almost exclusively in combination with a handful of stems, and most of the time you’ll see the past/attributive form びた or the te-form びて + auxiliary verb. The dictionary form びる is somewhat rarer but still appears in modern writing.

How to form びる / びて / びた

Attach びる directly to the stem of a limited group of nouns or adjectival roots. It conjugates as a regular ichidan (ru-verb).

古(ふる)びる → 古(ふる)びて → 古(ふる)びた

Common conjugations:

びる — dictionary form (rare on its own outside formal texts)
びて — te-form; often followed by いる, 見える(みえる), or used as connective
びた — past / attributive form; frequently modifies nouns to describe a quality (e.g. ひなびた旅館(りょかん), 古び(ふるび)た建物(たてもの))
びている — progressive/state “is looking ~”

[Noun/Adjectival stem] + びる
Examples: 古(ふる) + びる → 古びる(ふるびる), 大人(おとな) + びる → 大人びる(おとなびる), 田舎(いなか) + びる → 田舎びる(いなかびる)

⚠️ Not productive: You cannot freely create new びる words. Only a handful of stems have this suffix, and using it with a word like “かっこいい” would be ungrammatical and unnatural. Stick to the established set.

When is びる / びて / びた used?

Use びる / びて / びた in situations like:

describing the atmosphere or visual impression of a place (古び(ふるび)た、田舎び(いなかび)た)
commenting on someone’s apparent maturity or age (大人び(おとなび)た)
conveying a sense of rusticity, wear, or old-fashioned feel

Tone and register:

slightly literary or descriptive; common in travel writing, character descriptions, and narrative prose
not impolite, but feels natural in written registers more than in casual banter
Appears in JLPT N1 reading sections where the author paints a scene

N1 reflection

After reading each sentence, ask what job びる / びて / びた is doing: describing an inherent quality of appearance or atmosphere, not an act. That makes the nuance easier to remember than a one‑word translation.

Nuance of びる / びて / びた

The key nuance is inherent appearance or feeling, not pretense. Unlike the very similar pattern ～ぶる, which implies someone is actively putting on a certain air, びる suggests the quality is simply what you see — it’s not a show.

This matters because learners often translate these forms too literally. A pattern that looks like “seems” could easily be confused with “acts like,” but びる is firmly in the realm of passive impression. The quality belongs to the thing or person, not to an intentional performance.

For example:

大人び(おとなび)ている → Looks mature (maybe intimidating or reassuring, but not trying to be mature).
大人(おとな)ぶっている → Acts mature (possibly annoying — they’re putting it on).

The nuance shifts the entire emotional weight of the sentence.

びる / びて / びた vs ぶる / ぶって / ぶった

Both びる / びて / びた and ぶる / ぶって / ぶった attach to a stem and mean something like “seem like / act like,” but they differ in a crucial way.

びる / びて / びた

inherent appearance; the impression you get from the outside

Used when the quality seems natural to the subject, without effort or pretense.

大人びた態度

a demeanor that naturally appears mature

ぶる / ぶって / ぶった

deliberate pretense; putting on airs

Used when someone is consciously trying to look a certain way, often with a negative or sarcastic tone.

大人ぶる

to act grown‑up / put on a mature act

Quick contrast:

古びた建物 (a building that looks old — no pretension)
高慢ぶる (to act arrogant — conscious behavior)

Is the sentence describing a visual impression, or does it carry a hint of judgment about someone’s behavior? That single clue often picks the right pattern.

Common mistakes with びる / びて / びた

Watch out for these mistakes:

❌

彼はかっこびる。

Trying to attach びる to かっこいい — not one of the allowed stems.

✅

彼はかっこつけている。

Use a different expression for “acting cool.”

❌

少女は大人ぶっているけれど、自然に見える。

ぶる implies pretense, so “looking natural” contradicts it.

✅

少女は大人びていて、自然に見える。

❌

町が古ぶっている。

古(ふる)ぶる is not a recognized compound; use 古びる(ふるびる).

✅

町が古びている。

A helpful practice method is to write one sentence with びる and then try to force ぶる into the same meaning. If the tone changes from “impression” to “pretense,” you’ve felt the boundary.

Is びる / びて / びた on the JLPT?

Yes. **びる / びて / びた** is a confirmed JLPT N1 grammar point, though it appears less frequently than heavy‑hitters like ～まい or ～べからず.

For test preparation, study the pattern in full sentences and note the collocations. JLPT N1 questions often test whether you understand the surrounding context, not just the dictionary meaning.

Learning path for びる / びて / びた

Contrast it with related patterns like ~ぶる and ~がる to solidify the boundaries. Check the comparison notes in this post.

ぶり／っぷり — also attaches to stems to indicate manner or degree, but from a different angle
べくして — expresses an inevitable result, appearing in similar descriptive contexts
ぶる／ぶって／ぶった — the deliberate‑pretense counterpart to びる; mastering both clarifies the boundary
べくもない — shows impossibility, often used in formal, written registers like びる
