Grammar Book

GrammarBook: い-adjective + そうです (I heard that [I-adjective])

  • 18 Aug, 2026
  • Com 0

N4-G-065

い-adjective + そうです (I heard that [I-adjective])

Core / Hearsay & Reporting Information

👀 Layer A: Visual Guide



📝 Quick Summary

This grammar pattern connects an い-adjective in its Plain Form directly to そうです to express hearsay (“I heard that…”, “They say it is…”). It allows you to pass along reported information about a quality, price, or condition.

Structure: [い-adjective Plain Form] + そうです
Example 1: れびゅーによると、この おみせは おいしい そうです (According to the review, I heard this shop is delicious).
Example 2: たなかさんによると、あの ほてるは たかい そうです (According to Tanaka-san, I heard that hotel is expensive).

🔗 Connected Grammar:

  • N4-G-064: Verb (plain form) + そうです (Hearsay: I heard [Verb])
  • N4-G-066: な-adjective + だ そうです (Hearsay: I heard [Na-adj])
  • N4-G-067: Noun + だ そうです (Hearsay: I heard [Noun])
  • N4-G-037: い-adjective (drop い) + そうです (Conjecture: Looks [I-adj])

🔍 Layer B: Deepening

💡 Raya’s Hack

The Ultimate Rule: Keep “い” vs. Drop “い”!
The presence or absence of the letter い (i) completely changes the meaning of your sentence:

– Keep “い” + そうです (Hearsay): おいしい そうです (I heard it is delicious).
– Drop “い” + そうです (Conjecture): おいし そうです (It looks delicious right now).

When reporting information you read or heard from others, always keep the final い intact!

🚧 Joy’s Mistake

Scene: Joy is reporting to Ken about a luxury hotel he read about in a magazine.

Joy: 「あの ほてるは たかそう です。」
(Ano hoteru wa takasou desu.)

❌ Dropped “い” when reporting hearsay!

Why?

By dropping i to say takasou desu, Joy said “That hotel looks expensive” based on its visual appearance. To report information read in a travel book (“I heard that hotel is expensive”), he MUST keep the trailing い (takai).

Correct: 「あの ほてるは たかい そうです。」 (I heard that hotel is expensive.)
