“〜sou da”: Appearance (Looks) vs Hearsay (I Hear) — A Complete Distinction [JLPT N4]

Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026

「雨が降りそうだ」vs「雨が降るそうだ」 — same word, but the meaning and connection are worlds apart.

「おいしそう」 or 「おいしいそう」? — one 「そうだ」, two meanings

The same 「そうだ」: attached as 「おいしそう」 it's “looks tasty,” but as 「おいしそう」 it's “I hear it's tasty” — one character of attachment apart, opposite meanings (one you see, one you're told). 「そうだ」 has two totally different uses — appearance (looks like ~) and hearsay (I hear ~) — told apart by attachment. This is the “master distinction” guide — the attachment rules and how to judge, at once (each use has its own 〈appearance〉/〈hearsay〉 guide).

Core: tell appearance from hearsay by “attachment”

「そうだ」's two uses hinge on what form it attaches to:

Rule of thumb: “short (stem) = appearance, long (plain form) = hearsay.” Clearest with verbs: 降り (appearance) vs 降る (hearsay).

Attachment compared

key differencestem vs plain form降り vs 降る (looks like rain vs I hear it'll rain)

Examples in context

⚠️ Easy traps to avoid

Adjectives: drop い = appearance, keep い = hearsay. おいしそう (drop い, looks tasty) vs おいしいそう (keep い, I hear it's tasty). One 「い」 apart, opposite meanings. The classic trap.

Verbs: ます-stem = appearance, dictionary = hearsay. 降りそう (looks about to fall) vs 降るそう (I hear it'll fall). Appearance drops the 「る/ます」; hearsay keeps the full dictionary form.

Hearsay often pairs with 「によると」, appearance with the scene before you. Seeing dark clouds → 「降りそう (appearance)」; reading the news → 「降るそうだ (hearsay)」. A source (によると) = hearsay; judging by what's before you = appearance.

🔄 Compare with similar forms: appearance-そうだ/hearsay-そうだ/ようだ・らしい

💡 An exam judgment tip

For 「そうだ」's two uses, one rule of thumb keeps you right: “short = appearance (looks like), long = hearsay (I hear).” Adjectives, watch the 「い」: おいしそう (drop い = looks like), おいしそう (keep い = I hear); verbs, watch the form: 降りそう (ます-stem = looks like), 降るそう (dictionary = I hear). A judging trick: by what's before your eyes = appearance; with a source (によると) = hearsay. This is the “master distinction” — for each one's attachment details, negatives, and exceptions (よさそう), see the 〈appearance-そうだ〉/〈hearsay-そうだ〉 guides. Grasp “stem vs plain form” and the two そうだ never blur again.

❓ Questions you might have

Q: Fastest way to tell appearance from hearsay そうだ?

By the length of the attachment: attaches to a “stem” (short) = appearance (looks like); attaches to the “plain form” (long, full) = hearsay (I hear). Clearest with adjectives: おいしそう (drop い, short → appearance) vs おいしいそう (keep い, long → hearsay). Verbs: 降りそう (ます-stem, short → appearance) vs 降るそう (dictionary, long → hearsay). Rule of thumb: “short looks like, long I hear.” Plus one clue: a source like 「によると」 = hearsay.

Q: Why does 「そうだ」 have two totally different meanings?

Because they're actually two different 「そうだ」s that happen to be written the same. Appearance-そうだ comes from “judging by how it looks”; hearsay-そうだ from “(hearing) it said that way” (relaying). Japanese separates them by attachment: appearance to the stem (降り), hearsay to the plain form (降る). So despite the same form, checking what it attaches to and whether there's a source tells you “looks like” or “I hear.” A favorite JLPT distinction point.

Answer Explanations

1. (B) そうだ ── appearance-based そうだ: for an い-adjective, drop い and add そう. おいし (drop い) + そうだ.

2. (A) そう ── hearsay そうだ: verb plain form + そう. 「晴れそうです」. らしい also works, but 天気予報によると commonly pairs with hearsay そうだ.

3. (B) ── おいしそうだ (drop い) = appearance (your own observation); おいしいそうだ (keep い) = hearsay (something you heard from others).

4. (A) なさ ── the appearance form of 「ない」 is the special form なさそうだ. 「問題なさそうだ」.

5. (B) そう ── appearance-based そうだ: verb ます-stem (drop ます) + そう. 落ちます→落ち→落ちそうだ.
