が with 好き, ほしい, できる, 分かる | Japanese Grammar

English speakers hit a wall the first time they try to say "I understand Japanese." The natural instinct is 日本語を分かります — Japanese is the object, 分かる is the verb, so surely を? It is wrong. The correct sentence is 日本語が分かります, with が. And it is not a one-off exception: a whole family of Japanese predicates — liking, skill, wanting, ability, understanding, and perception — marks the thing English treats as a direct object with が, not を. This page shows you why, and hands you one mental trick that makes the entire class fall into place at once.

The pattern

These predicates all take が where English uses a transitive verb with an object:

Predicate	Type	Meaning	Marks its "object" with
好き / 嫌い	な-adjective	like / dislike	が
上手 / 下手	な-adjective	good at / bad at	が
ほしい	い-adjective	want (a thing)	が
できる	verb	can do / be able	が
分かる	verb	understand	が
見える / 聞こえる	verb	be visible / audible	が
〜たい (desiderative)	い-adjective ending	want to (do)	が (もを)

Notice these are not all the same part of speech — some are な-adjectives (好き, 上手), one is an い-adjective (ほしい), some are verbs (分かる, できる). If the adjective terminology is new, see the two adjective classes. What unites them is not their grammar class but their meaning: every one describes a state, not an action.

The one trick: read them as states

Here is the mental move that dissolves the whole problem. Do not translate these predicates as English transitive verbs. Translate them as descriptions of the thing itself:

好き is not "like" but "is likeable / pleasing"
できる is not "can do" but "is doable / possible"
分かる is not "understand" but "is understandable / clear"
ほしい is not "want" but "is wanted / desirable"
見える is not "see" but "is visible"

Under that reading, the が makes complete sense: the thing is the subject of a state. りんごが好き is not "I like apples" but "apples are pleasing [to me]." 日本語が分かる is "Japanese is clear [to me]." The person doing the liking or understanding is the experiencer, usually left unstated or marked as the topic with は — and the thing they relate to is grammatically the subject of the state, which is why が is its natural home. English buries this by forcing a transitive verb ("I like / I understand"); Japanese wears it on its sleeve.

猫が好きです。

neko ga suki desu

I like cats. (Cats are pleasing [to me].)

日本語が分かります。

nihongo ga wakarimasu

I understand Japanese. (Japanese is clear [to me].)

料理が上手ですね。

ryōri ga jōzu desu ne

You're good at cooking, aren't you? (Cooking is well-done [by you].)

💡

Whenever a predicate describes a state you're in relative to a thing — you find it likeable, doable, clear, visible, desirable — the thing is the subject of that state and takes が. If you can rephrase the English as "X is [likeable / possible / understandable / wanted]," you have confirmed が.

Liking and skill: 好き・嫌い・上手・下手

The な-adjectives of preference and ability are the most common members of the class. The thing liked or the skill area takes が; the experiencer, if named, takes は.

私は辛い物が好きだけど、妹は甘い物が好き。

watashi wa karai mono ga suki dakedo, imōto wa amai mono ga suki

I like spicy food, but my little sister likes sweet things.

兄は運転が下手で、いつも道に迷う。

ani wa unten ga heta de, itsumo michi ni mayou

My older brother is bad at driving and always gets lost.

This is also a textbook double-subject shape: 私は…が好き is "as for me, … is pleasing." The は frames the experiencer, the が marks the thing — two layers, exactly as in 象は鼻が長い. If that structure feels shaky, the は vs が page lays it out.

Wanting a thing: ほしい

ほしい means "want," but crucially it wants a thing (a noun), and that thing takes が.

新しいパソコンがほしい。

atarashii pasokon ga hoshii

I want a new laptop.

今、一番ほしいものは時間です。

ima, ichiban hoshii mono wa jikan desu

What I want most right now is time.

Two cautions. First, ほしい is for wanting a noun; to want to do an action, you switch to the 〜たい ending below. Second, plain ほしい describes your own desire — to report someone else's wanting you generally need ほしがる. Both points get their own page: 〜がほしい: wanting a thing.

Ability and potential: できる and 〜られる

できる ("can do / be able") and the potential form of any verb (泳げる "can swim," 話せる "can speak") mark what you are able to do with が. This catches learners off guard because the potential is built from a transitive verb that took を in its plain form.

弟は英語がぜんぜんできないんです。

otōto wa eigo ga zenzen dekinai n desu

My little brother can't speak English at all.

ここから富士山が見える日は、車の運転ができない。

koko kara Fujisan ga mieru hi wa, kuruma no unten ga dekinai

On days you can see Mt. Fuji from here, I can't drive.

Watch the plain-to-potential shift: パンを食べる ("eat bread," を) becomes パンが食べられる ("can eat bread," が). The moment a verb goes potential, its object tends to flip from を to が, because "can eat X" describes X as edible-to-me — a state again. This flip is important enough to have its own treatment: potential + が for the object.

Perception: 見える and 聞こえる

見える ("be visible / can be seen") and 聞こえる ("be audible / can be heard") are spontaneous perception verbs — the sight or sound presents itself to you — so the thing perceived takes が.

海が見えるホテルに泊まりたい。

umi ga mieru hoteru ni tomaritai

I want to stay at a hotel where you can see the sea.

隣の部屋から変な音が聞こえる。

tonari no heya kara hen na oto ga kikoeru

I can hear a strange noise from the next room.

These differ from 見る (to look at) and 聞く (to listen to), which are genuine transitive actions and take を. 音楽を聞く is "listen to music" (deliberate action, を); 音が聞こえる is "a sound is audible" (it reaches you on its own, が). The を verbs get their own home on the を direct-object page.

The contrast that makes it click: を vs が

Put a plain transitive action beside its stative cousin and the logic is unmistakable:

毎朝コーヒーを飲みます。

maiasa kōhī o nomimasu

I drink coffee every morning. (a habitual action — を)

のどが渇いた。冷たい水が飲みたい。

nodo ga kawaita. tsumetai mizu ga nomitai

I'm thirsty. I want to drink some cold water. (a desire — が)

コーヒーを飲む is an action: you actively drink. 水が飲みたい is a state of desire: water is drink-want-worthy to you right now. Same verb 飲む, different particle, because one reports doing and the other reports wanting.

The honest complication: を with 〜たい

Now the point where I will not pretend the rule is airtight. With the 〜たい desiderative, both が and を are heard in real life. The traditional, textbook-correct choice is が (水が飲みたい), and it is never wrong. But を (水を飲みたい) is extremely common in modern speech and writing, and it is actually preferred when:

the object is separated from たい by other words, or the verb phrase is long, or
the focus is on the action rather than on the object as a craved thing.

今日は映画を見たい気分だ。

kyō wa eiga o mitai kibun da

I feel like watching a movie today.

So with 〜たい, treat it as が is safe and traditional, を is natural and increasingly standard. This flexibility is unique to 〜たい — it does not extend to 好き, できる, 分かる, ほしい, or 上手, where を is simply wrong. The full breakdown of when speakers pick which lives on を vs が with potentials and 〜たい, and the desiderative itself is on 〜たい: your own desire.

💡

Split the class in two. With 好き・できる・分かる・ほしい・上手 — always が, を is an error. With 〜たい only — が is traditional, を is common and fine. Don't over-apply the flexibility of 〜たい to the rest of the family.

Common mistakes

❌ 日本語を分かります。

Incorrect — 分かる is stative; the thing understood takes が.

✅ 日本語が分かります。

nihongo ga wakarimasu

I understand Japanese.

❌ 私はスポーツを上手です。

Incorrect — 上手 describes a state; the skill area takes が.

✅ 私はスポーツが上手です。

watashi wa supōtsu ga jōzu desu

I'm good at sports.

❌ 新しい車をほしいです。

Incorrect — ほしい takes its wanted thing with が, never を.

✅ 新しい車がほしいです。

atarashii kuruma ga hoshii desu

I want a new car.

❌ 私はピアノを弾くことをできます。

Incorrect — the ability's object takes が: ピアノを弾くことができます, or simply ピアノができます.

✅ 私はピアノを弾くことができます。

watashi wa piano o hiku koto ga dekimasu

I can play the piano.

❌ 音楽が聞きました。

Incorrect — 聞く (to listen deliberately) is a transitive action and takes を; only spontaneous 聞こえる takes が.

✅ 音楽を聞きました。

ongaku o kikimashita

I listened to music.

The two errors to burn out of your reflexes: 好き/上手/ほしい/できる/分かる never take を, and the transitive perception verbs 見る/聞く do take を while their spontaneous partners 見える/聞こえる take が. Get those and you have the class.

Key takeaways

A family of predicates — 好き, 嫌い, 上手, 下手, ほしい, できる, 分かる, 見える, 聞こえる — marks its "object" with が, not を.
They all describe states, so read them as "X is [likeable / possible / understandable / wanted / visible]" — the thing is the subject of the state.
The experiencer is usually the topic (は) or unstated, giving the 象は鼻が長い double-subject shape.
The potential form flips its object to が: パンが食べられる.
〜たい is the one flexible case: が is traditional, を is common. The rest of the class rejects を outright.
