Plain form + noun

A whole clause can modify a noun. The clause goes before the noun, verb in plain form.

ClauseModified noun

Subject inside the clause: が (or の)

Inside a modifying clause the subject takes が, never は. の is an accepted alternative: 母ははの作つくった料理りょうり.

Adjectives modify the same way

Why there is no 関係代名詞かんけいだいめいし(relative pronoun)

English hangs a modifying clause behind the noun and glues it on with "who", "which" or "that". Japanese does the opposite: the clause goes in front, and nothing joins them at all.

EnglishJapanese
the book that I bought yesterday
the person who goes to Kyoto
the town where I live
the day when we met

"who / which / where / when" all collapse into the same shape. Do not look for a word to translate them with — there is none.

The head noun keeps its role inside the clause

The modified noun is understood as filling one of the clause's own slots. The same clause plus a different head noun gives a completely different phrase.

PhraseRole of the head nounMeaning
subject (が)the person who borrowed the book
object (を)the book I borrowed from someone
place (で)the shop where I bought the book
time (に)the day I bought the book
reasonthe reason I bought the book

Because the link is never spelled out, the phrase alone can be ambiguous — is normally 'the person who took the photo', but context decides. Japanese leans on context here where English forces you to choose a pronoun.

Full form chart — what goes immediately before the noun

Everything is plain form. The only shapes worth memorising are the two in the top-right corner.

Typenon-pastnegativepastpast neg.
verb +人ひと
い-adj +本ほん
な-adj +町まち
noun +本ほん

な-adjectives and nouns swap だ for な / の in the non-past affirmative only. Everywhere else the plain form is used untouched. ✕ · ○ · ○

ます-form never appears before a noun. ✕ → ○ — even when the sentence around it is polite.

が → の inside the clause

The subject of a modifying clause takes が. In short clauses it may be swapped for の with no change in meaning — a very common move in speech.

がのBoth fine?
yes — short clause
yes — set phrase, both common
の gets awkward once the clause is long

Never は on the subject. は marks the topic of the whole sentence, and a modifying clause is not a sentence: ✕ · ○.

は can still turn up inside a modifier — on a place or a time, where it is contrast rather than topic (L27): · . So は is not a full stop: what it can never be inside a clause is the subject marker.

Avoid の when it could be read as possession: is fine, but with a noun that could belong to 山田さん, が is clearer.

Reading strategy: find the verb, then look right

Long Japanese sentences are mostly stacked modifiers. Parsing one is mechanical: a plain-form predicate that is not followed by 。/が/けど/から is modifying whatever noun comes next.

StepOn
1. find a plain predicate
2. take the next noun
3. everything before it is the clause
4. the real sentence is

Modifiers nest freely: — 'the company where the person I met last week works'.

Where the modified phrase can sit

A modified noun is still just a noun, so it takes any particle and fills any slot.

SlotExample
は / が
を
に / へ / で
predicate (です)
with a counter
Nouns that live on modifying clauses

Some nouns are almost always preceded by a clause. Learn them as patterns rather than as vocabulary.

NounPatternExample
dict. + 時間じかんがない
dict. + 用事ようじがある
dict. + 約束やくそくがある
dict. + 予定よていだ
dict. + 仕事しごと

The same slot later takes こと and の as pure nominalisers — (L18), (L38).

ている in modifiers: state vs action
PhraseReading
state — the person who wears glasses
in progress — the person who is running
state — a married person
state — someone I know

Clothing verbs are all state verbs in this pattern, which is why the description of a person almost always uses ている: .

Describing a person — the L22 workout

Note how (L16) chains two descriptions before the head noun. Modifiers combine with every connector you already know.
