Verb or い-Adjective + ようだ

Used to describe something that appears or seems to be a certain way based on observation or information. It can also express that something is like or similar to something else.

Verb (Informal Form)

Attach ようだ directly to the informal form of a verb to express a likelihood or appearance of an action.

It seems that it will rain.

It seems he didn't go to the hospital.

い-Adjective

Attach ようだ directly to the informal form of an い-Adjective to express how something seems.

It seems to be cold outside.

Note

ようだ behaves like a な-Adjective. When it modifies a noun, use ような. When it modifies a verb or adjective, use ように. In casual speech, ように is often replaced by みたいだ.

Noun or な-Adjective + ようだ

Used when a noun or a な-Adjective is the basis for the appearance or comparison.

Noun + の

Use the particle の between a noun and ようだ to show similarity or appearance.

It is like a dream.

That person is like a teacher.

な-Adjective + な

Keep the な when attaching ようだ to a な-Adjective to express how something appears.

It seems to be quiet.

Note

When using a noun to say something is 'like' that noun, the particle の is mandatory. For な-Adjectives, the な is mandatory.
