How to use ~そう (~sou): A Streetwise JLPT N4 Grammar Guide

sou

見張みはりのおとこねむそうだ。
The lookout looks sleepy.

Read the explanation below to understand the nuance of how this grammar structure is used.

This ain’t the 「そうだ」 you use when you’re repeating gossip you heard on the street. Nah, this is the one you use when you’re eyeballing a situation yourself. It’s for when something looks a certain way, or seems like it’s about to happen. It’s your “vibe check” grammar.


Look, ~そう is all about your first impression based on what you see. It’s your gut feeling from a visual.

You’re looking at something or someone and making a quick judgment. You see clouds rollin’ in, dark as hell? It looks like it’s gonna rain (あめりそうだ). You see a dude sweatin’ bullets while the feds are asking questions? He looks nervous (緊張きんちょうしてそうだ).

It’s not about facts. It’s not about what you know. It’s about what shit looks like on the surface. You’re sizing up the scene, straight up.


You use this all the time. Imagine your boy walks in after a brawl, his face all busted up. You’d say, 「いたそう!」 – “That looks painful!” You don’t know if it hurts, maybe he’s built different, but damn, it looks like it does.

Or you see the new guy in the crew, lookin’ all shaky before his first big job. You turn to your partner and say, 「あいつ、ビビってそうだ」 – “He looks scared.” It’s what you see right now.


Think of ~そう as the “vibe check” grammar.

When you roll up to a club, you check the vibe, right? You look at the bouncer. He’s got his arms crossed, mean-muggin’ everybody. You don’t know he’s a hard-ass, but he damn sure looks like one.

That bouncer is 「きびしそう」 – he looks strict. ~そう is that instant read you get just by lookin’. It’s the trailer, not the whole movie.


Grammar Conjugation Guide.

Read the table below then use it to conjugate some words you know.

Here’s the breakdown on how to build this thing.

TypeHow to ChangeExampleTranslation
I-AdjectiveDrop the final い (i)いそがしい
-> いそがしそう
Looks busy
Na-AdjectiveDrop the な (na)大変たいへん 
-> 大変たいへんそう
Seems tough
Verb (V-Stem)Use the masu-stem (drop ます)たおれます
-> たおれそう
Looks like they’ll fall
Exception: いいnew formいい
-> よさそう
Looks good
Exception: ないnew formない
-> なさそう
Doesn’t seem to be

It’s pretty simple. For I-adjectives, you just chop off that last “i” and slap ~そう on it. からい (karai – spicy/tough) becomes からそう. For Na-adjectives, just add ~そう to the root. 心配 (worry) becomes 心配しんぱいそう. For verbs, you use that stem form, the one you use for ~ます. はじまる becomes はじまりそう – “looks like it’s gonna start.”

Pay attention to the exceptions, though. You can’t say 「いそう」 for “looks good.” That’s wack. You gotta use the OG form, い, and flip it to よさそう. And for the negative “doesn’t look like,” you take ない and make it なさそう. Like 「かねなさそう」- “He looks broke.”
