Understanding the difference between そうです (様態) (sou desu (youtai)),そうです (伝聞) (sou desu (denbun)), and ようです (you desu) is one of the most important distinctions in Japanese grammar. This comprehensive guide will help you master when and how to use each one correctly.
Grammar Point A
そうです (様態) (sou desu (youtai))
Looks like / Seems like (visual appearance)
Based on direct visual observation. Describes how something LOOKS right now.
ない takes なさ + そう = なさそう (looks like there isn't / doesn't look like).
Mistake #5Using らしい as if 100% certain: 「会議は3時らしい」when you know for sure
Correction: 会議は3時です (if you know) / 会議は3時らしいです (if uncertain)
らしい implies uncertainty. Don't use it for facts you're sure about.

Frequently Asked Questions
Check the grammar! Appearance-そう attaches to STEMS: おいしい → おいしそう. Hearsay-そう attaches to PLAIN FORMS: おいしい → おいしいそうです. If you see the full word before そう, it's hearsay.
They're very similar! ようです is slightly more formal/written. みたいです is more casual/spoken. Both express inference. In JLPT tests, treat them as interchangeable unless formality matters.
Generally no. らしい implies you got the information from somewhere else. If you witnessed something directly, use ようです for inference or state it directly.
いい is actually a contracted form of よい. For grammatical forms that attach to stems, the original よ- base appears: よ + さ + そう = よさそう. Similar to how いい → よく for adverb form.
らしい often implies information from an external source (heard from someone). みたい is more about the speaker's own observation or impression. But in casual speech, they're often used interchangeably.
Summary

Pro Tip: The best way to master the difference is through reading and listening practice. Pay attention to how native speakers use these grammar points in context.
