"Is composed of," "consists of" and "comprised of" are all roughly interchangeable, and there's no difference between them in practice.

I would use "at," but there's usually two streets when we talk about corners. For example, "At the corner of Martin Street and Rains Street." I think "on" is acceptable too though; "at" would just sound more natural to me.

Phuong is right. I feel like the person you were speaking with had a hard time understanding your sentence, and the "What?" was them wanting to clarify what you meant rather than them taking offense.

However here actually does fit the dictionary definition! Appending "however" to the end of a statement is essentially the same as using it at the beginning of it.

For example, "The classic cork stopper does have its advantages, however" and "However, the classic cork stopper does have its advantages" are interchangeable.

In terms of whether or not it contrasted from the previous sentence, one would need to see it in context. If it were preceded by something along the lines of "Many do not prefer the classic cork stopper," then it would make sense. If you started a paper off or wrote "However" in the sentence without any context, however, this wouldn't make sense.

Hopefully this helps!

I feel exactly the same way! The gender roles society has ascribed to both men and women are archaic and horrible, and I feel like every step we take toward moving beyond them is great.

In addition to this, the fixation on looking and being perfect that many people seem to have today is very unhealthy. To an extent, caring about your body and appearance and having an interest in fashion can be good, but at a certain point it becomes more harmful than helpful.

I'm not sure if taking one or two lessons per week and not doing any additional work or studying outside of lessons, even with an excellent teacher, would be the optimal way to learn. I don't want to say that it's not possible, since everyone has a different learning method that works best for them, but for most students I feel like more practice is needed, daily if possible. This includes things like keeping a journal in their target language, reviewing vocab, homework assignments, etc.

With individual study and the one or two lessons every week together however, I feel like that would be a great way to learn a language, and it would be more than possible. In fact, I feel like one doesnt even need a teacher if they have enough drive and motivation to do enough independent study, though they do make things much easier.

I feel like it really comes down to the pace at which a student wants to learn a language. If they want to learn it quickly and intensively, one or two lessons per week and rigorous studying and practicing every day may be a good option. For others, they may want to take things slower and only want to study a few days a week non-intensively and not take lessons.

On how I would do it, I've been learning Japanese on and off for a while now, but only recently have I considered taking lessons (though I cannot right now due to my financial situation). I review my vocabulary and practice daily with Duolingo, Quizlet and other applications and I recently began chatting with a conversation partner I met on here. I also occasionally will write poetry or a journal entry in Japanese just to learn new vocabulary and practice what I know.

I never took lessons in German up until university, and I arrived at a B2 level just through the method I described above. Granted it was a very slow process and took me from middle school until the end of high school (my practice and interest in the language has been very sporadic), but it did indeed work.

I'm no native speaker and you may be more advanced in Japanese than I am, so take my response with a grain of salt.

I believe it just depends on the context. If your friend were talking about their mother and you wanted to bring up yours, I think "私のお母さん" would be the better choice. If it's obvious from the context that you would be talking about your mother, I believe "お母さん" would sound more natural, as the "私の" might come off as redundant.

You may want to wait for a native speaker to answer though. This is just an educated guess based on what I've learned so far.

EDIT: Just as I posted, someone else answered. Disregard this!
