첫번째는 학교문법이라는걸 만든 작자들이 해외에서 쓰던 용어들을 지네 맘대로 가져다 써버린 탓에 외국어 공부를 하다보면 헷갈리게 되는거고, 두번째는 학교에서 문법을 가르칠때 정의를 설명하기 보다는 그냥 그렇다니까 외워라는 식으로 가르치니까, 세번째는 문법 공부는 평생 하더라도 정작 문법에 대한 공부는 어문어학과나 언어학과를 가지 않는 이상 고등학교때 끝나는 경우가 많으니까?

맞음 근데 왜 보조사인지 명확히 배운적은 없는거 같음

그치만 왜? 라는거 안가르쳐주니까 저런 생각을 하는걸지도

우리나라 교육은 병신이야!

The topic of a sentence is distinct from the grammatical subject. The topic is defined by pragmatic considerations, that is, the context that provides meaning. The grammatical subject is defined by syntax. In any given sentence the topic and grammatical subject may be the same, but they need not be. For example, in the sentence "As for the little girl, the dog bit her", the subject is "the dog" but the topic is "the little girl".

Topic being what is being talked about and the subject being what is doing the action can, also, be distinct concepts from the concept agent (or actor)—the "doer", which is defined by semantics, that is, by the contextual meaning of the sentence in the paragraph. In English clauses with a verb in the passive voice, for instance, the topic is typically the subject, while the agent may be omitted or may follow the preposition by. For example, in the sentence "The little girl was bitten by the dog", "the little girl" is the subject and the topic, but "the dog" is the agent.

그래서 주어는 무조건 행위자임?(주격으로써의 주어를 말하는거지 행위자로써 주어를 말하는게 아님)

A topic marker is a grammatical particle used to mark the topic of a sentence. It is found in Japanese, Korean, Quechua, Ryukyuan, Imonda and, to a limited extent, Classical Chinese. It often overlaps with the subject of a sentence, causing confusion for learners, as most other languages lack it. It differs from a subject in that it puts more emphasis on the item and can be used with words in other roles as well.

Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees (John is but John and Mary are). If there is no verb, as in Nicola – what an idiot!, or if the verb has a different subject, as in John – I can't stand him!, then 'John' is not considered to be the grammatical subject, but can be described as the topic of the sentence.

그래서 주제는 격이 없음? 행위자가 아닌주제가 주격으로써의 주어가될순었음?

Many synthetic languages such as Latin, Greek, Persian, Romanian, Assyrian, Assamese, Russian, Turkish, Korean, Japanese, Finnish, Arabic and Basque have no strict word order; rather, the sentence structure is highly flexible and reflects the pragmatics of the utterance. However, also in languages of this kind there is usually a pragmatically neutral constituent order that is most commonly encountered in each language.
