みたいLike, Similar to, Resembling

どうやら and みたい combine to convey a tentative impression or guess based on observed clues. どうやら adds a tone of cautious inference, while みたい expresses resemblance or appearance. For example: どうやら彼は来ないみたいだ (It seems like he’s not coming).3

The みたい in all these patterns means 'seems like (A)' or 'like (A)'. The difference lies in how it connects to other words. Examples include 春みたい or 春みたいだ／です ('It's like spring.'), 春みたいな天気 'spring-like weather', and 春みたいに暖かい ('It's warm like spring.').

Both らしい① and みたい express similarity, but with different nuances. らしい means something is typical or characteristic of what it represents, e.g. 春らしい天気 which implies 'weather that's just like spring should be'. In contrast, みたい suggests resemblance of one thing to something else that it is not, e.g. 春みたいな天気 'spring-like weather' such as an unseasonably warm day in winter.

にみえる and みたい both express that something 'seems' a certain way, but with different nuance. にみえる specifically refers to visual appearance, e.g. 'looks like', and can be used with そうだ or ようだ. みたい means 'is like' or 'seems like' more in a more general sense, not necessarily related to appearance, and is more casual than にみえる.

Both みたい and ようだ express resemblance, like 'seems like' in English. みたい is more casual and common in speech, while ようだ is more formal and used in writing. みたい follows nouns directly (e.g. 春みたい), while ようだ requires の (e.g. 春のようだ). Both function grammatically as な-adjectives.

Both みたい and そう can mean 'seems like', but differ in nuance and usage. みたい compares something to another, e.g. 春みたい ('It's like spring.') or is based on reliable evidence, e.g. 面白いみたい ('Apparently it's interesting.' i.e. based on something you've heard). そう is based on appearance or sensory impression, e.g. 面白そう ('It looks/sounds interesting.').

Both みたい and そうに・そうな can mean 'seems like', but differ in nuance and usage. みたい expresses resemblance to something else, e.g. 春みたいな天気 'spring-like weather'. そうに・そうな is based on sensory cues and often used with verbs, e.g. 雨が降りそうな天気 'weather that looks like it's about to rain'.

Both みたい and ように・ような express resemblance, similar to 'seems like' in English. みたい is more casual and common in everyday speech, while ように・ような is more formal and used in writing. みたい attaches directly to nouns, e.g. 春みたいな天気 'spring-like weather'. In contrast, よう requires の, e.g. 春のような天気 (same meaning).
