In the the example:
こういち みたいに 、日本語にほんごを教おしえたい。
What is みたい attaching to such that it adds the に connector rather than the な？
The Seemingly obvious answer is that it is 日本語 but then is should be な as that is the noun connector, yet it is not. Is it because it is a dangling phrase or that みたいに is the nutreal conncetor? any help would be appreciated.
Hey! Sorry for the late reply! 
When you add に to なAdjective it will work like an adverb (adverbs can modify adjectives, adverbs and verbs).
So when みたいな modifies a noun, it describes similarity in appearance, and when it modifies a verb it describes similarity in a manner of doing something (but ように can also modify adjective to also describe similarity in appearance etc).
In this sentence, you have a noun 日本語 and verb 教える with auxiliary adjective たい to modify.
Japanese (language) in appearance similar to Koichi doesn’t really make sense.
But teaching Japanese (language) in the manner (like) as Koichi does makes one and that is what the speaker wants to express.
Is it clear now?
Yeah I think that clears it up, I will just have to see in through a few more reviews for it to sink in.
For this item, the grammar point makes a distinction between
This says that みたい is about appearance, while のよう means in the manner of.
However, I have been looking at the example sentences, and am seeing more のよう sentences than みたい sentences, so I think I’m not understanding the grammar point correctly yet.
For example, to swim like a fish (in appearance) would mean that one would swim, looking like they were a fish, as if they were dressed like a fish, rather than swimming like how a fish would swim.
For the next sentence, “Similarly to sandals, they are easy to put on.”, the closest this would get is that “similarly to sandals” only refers to “they” in appearance, and the easy to put on is irrelevant to the similarity. I would say that "in the manner of sandals, the are easy to put on.
What am misunderstanding here?
We had a discussion the other day about this. Hopefully this will connect the two threads
So am I correct in understanding from your post that this distinction is too strict?
I reached out to a native for this one as there seems to be a lot of subtleties and they agreed with the BP slight distinction that みたい can a bit more visual while のよう leans towards characteristic (along with colloquial vs. more written difference). Therefore the distinction of “appearance of” and “manner of” work out well for specific instances but not confined to these meanings.
But I believe when used for meanings of “like” or “similar to” (probably the majority of the time), they are interchangeable. I could not get a distinct answer when not use “x” but must use “y” and my teacher also gave the green light to interchange them. The Maggie Sensei entry for みたい and のよう didn’t throw any exceptions either from what I skimmed with many interchangeable examples. Looks like there are times when みたい can overlap with into “seems like” or “heard” for そう・らしい a bit more though. Contrary, I could see how のよう could have more conceptual applications or be written for instruction manuals or something.
For the sentences you mention above, I see no difference in interchanging them as both based on direct information.
Hey! Sorry for the slow response 
I have removed that part, it was an error. みたい and よう, as you said are basically identical. The よう being more formal, and よう having some other uses like “so that”, ように祈る、ようになる、ようにする where みたい doesn’t work.
It should be something like:
みたいな、ような -> appearance of (modifying nouns)
みたいに、ように -> in the manner of (modifying adverbs, adjectives, verbs)
I am really sorry for the inconvenience it caused!
What is the difference between the two?
Hey 
みたいな is adjective form (it is used to modify nouns)
みたいに is adverbial form (it is used to modify adjectives, verbs and other advers)
みたい(だ) is the predicative form used at the end of a sentence.
みたいに(and ように) is used in general to show the similarity of something to something else in appearance or in a manner of doing something.
みたい（and ようだ） also has this use + conjecture(possibility of something) (Feedback - Suggested Improvements/Feature Request)
Thank you. It might be a good idea to add that to their respective pages.
Done 
The discussion link from みたいに should probably link here. Currently it takes to a topic on てすみません.
I will do something about it!
PS
Your avatar is actually amazing >.<
Thank you! 
Hey and welcome on the community forums 
てほしい is only used for what we wish/demand from other people.
So:
(あなたに)この女みたいになってほしい
I want you to become like that woman.
If you want to speak about your own wishes you have to use: たい or Nounがほしい
私はあの女の子みたいになりたい。
I want to become like that woman.
ドクロストーンがほしいよ。
I want dokuro stone(item from anime - yattaman).
I hope it helps and if you have more questions feel free to ask,
Cheers
PS
This is a bit more advanced, but interesting. てほしい is also used when we wish for some events (that are beyond speaker will) to happen, like:
雨が降って欲しい.
I wish for rain.
(lit. I wish for rain to fall)
I see, thank you!
On the main page for this it says you can get the structure Verb + みたいに, but there aren’t any examples of this form, as far as I can tell. What would that construction be used for? Would it be used to say something like “His walking is like running for other people”?
Hey 
Good question
We will have to add examples for this usage!
That’s right! It is used to express resemblance of something to an action described by the verb.
It is easier to understand with a vivid example:
ペンギンは鳥類だけど飛べないよ。だけどまるで空を舞っているみたいに華麗に海中を泳ぐんだ。
Penguins are birds, but can’t fly. But they splendidly swim through the oceans as if soaring (flying) through the air.
I hope it helps!
Cheers
