Overview
yet （まだ）届いてないだけなんだよね。この yet という小さな単語は、英文法における究極の「待合室」みたいなもの。文の一番最後にちょこんと座っていて、「もうすぐ何かが起こるはず」という期待を合図しているんだ。これがないと、文がなんだか未完成に感じちゃう。逆にこれを使えば、ネイティブスピーカーみたいに自然に響くよ。Yet は、現在完了形 (Present Perfect tense) と一緒に使われる「時の副詞」だね。「今現在に至るまで、まだ起こっていないこと」を話す時に使うんだ。あと、「期待していたことがもう起こったか」を尋ねる時にも役立つよ。これは過去と「今この瞬間」をつなぐ架け橋みたいなもので、そのアクションが未来に起こりそうだというニュアンスを含んでいるんだ。YouTube動画の「ロード中... (loading...)」の文法版だと思ってくれればいい。会話に「まだかなー」という期待や焦りの気持ちをプラスしてくれるんだ。B1レベルにおいて、この yet をマスターするのは大きなマイルストーンになるよ。単純な過去形の文から卒業して、進行中の状況や、これから片付けるタスクについて話せるようになるからね。How This Grammar Works
yet は文末というスポットライトが大好きなんだ。ほぼ間違いなく、文の一番最後に見つかるはずだよ。具体的には2種類の文でよく顔を出す。1つ目は「否定文」、2つ目は「疑問文」だね。肯定文は苦手みたい。「I have eaten yet」なんて言ったら、みんな困惑した顔をするはず。これは聞き手への合図として機能して、「状況が変わるのをまだ待ってるんだ」と伝えているんだ。スマホでメッセージを確認するようなものだね。yet（まだ）受け取ってないけど、画面を見続けている状態さ。

When To Use It
yet を使おう。家事や仕事のタスクについて話すのにピッタリだね。人やイベントを待っている時にも使えるよ。SNSのコンテキストでも大活躍。「そのTikTok、yet (もう) 投稿した？」もししてないなら、フォロワーが退屈しちゃうかもね。ちょっとしたプレッシャーや緊急性を感じている時にも使う。Zoomでの就職面接でもよくあるよ。「yet (もう) このソフトウェアを使ったことはありますか？」旅行Vlogの王様でもあるね。「yet (まだ) 山頂には着いてないけど、この景色を見てよ！」単純な「いいえ (no)」を、「今のところはまだ (not for now)」というニュアンスに変えてくれるんだ。Politeness Levels
Social Context | Sentence | Tone
Casual (Texting a friend) | Haven't finished the show yet. | すごくカジュアル。主語を省略してるね。
Neutral (Standard conversation) | I haven't finished my homework yet. | フレンドリーで明確。
Formal (Job interview/Email) | We have not received the documents yet. | 真面目なトーン。短縮形は使わない。
Memory Trick
yet を Yelling End Tool （文末で叫ぶツール）だと覚えておこう。文の End （最後）に居座って、まだ何かを待っているんだと Yells （叫んで）いるわけ。ドアのそばに座っている犬みたいなものだね。yet （まだ）散歩には行ってないけど、準備は万端って感じ。
Common Mistakes
yet を入れちゃダメだよ。「I have seen the movie yet」とは言わない。良いニュース（もう完了したこと）には代わりに already を使おう。もう一つの大きな間違いは、yet を真ん中に置くこと。「I haven't yet seen it」は可能だけど、すごく堅苦しいんだ。B1英語レベルなら、安全策として文末に置いておこう。あと、yet と still を混同しないこと。Still は普通、動詞の前に来るけど、Yet の居場所はゴールライン（文末）だ。もし置く場所を間違えたら、ロボットみたいに聞こえちゃうかも。ちょっと壊れたロボットにね。そんなロボットにはならないで。Contrast With Similar Patterns
Yet vs Already: already は予想より早く起きたことに使う。yet はまだ起きていないけど、これから起きることに使う。Yet vs Still: Still は状況が望んでいるよりも長く続いていることを強調する。yet は完了を期待していることに焦点を当てる。Yet vs Just: Just は1分前に起きたことに使う。yet は今現在欠けていることに使う。

文化メモ
British speakers are very strict about using the Present Perfect with 'yet'. Using the Past Simple ('Did you do it yet?') sounds very American to them.
In casual American speech, the Past Simple is frequently used with 'yet'. It is not considered 'wrong' in conversation, but the Present Perfect is preferred in writing.
Using 'yet' in a professional context shows that you are aware of a deadline or expectation. It sounds more proactive than a simple 'no'.
From Old English 'giet' or 'gyta', meaning 'at this time' or 'hitherto'.

Generally, no. In standard English, we use `already` for positive sentences. However, in very formal English, you might see `I have yet to...`, but this actually has a negative meaning (I haven't done it).
`Not yet` is neutral and focuses on the expectation. `Still not` often sounds more frustrated or surprised that something is taking so long. Example: 'I haven't finished yet' (Neutral) vs 'I still haven't finished!' (Frustrated).
It is not wrong in American English conversation. However, in British English and on international exams like the TOEFL or IELTS, you should use the Present Perfect: `Have you finished yet?`.
In 99% of cases, `yet` goes at the very end of the sentence or clause.
No, we don't usually use `yet` with the Present Continuous. We use `still` for ongoing actions. Example: 'I am still working' (not 'I am working yet').
It's a very common and polite way to say 'No, but it will happen soon.' It's much more natural than just saying 'No' when someone asks if you've finished something.
It doesn't change the verb's meaning, but it changes the *aspect* of the sentence, adding the feeling of 'up to now' and 'future expectation'.
Yes, it is very common in formal reports to indicate that data is not available or a decision hasn't been made. Example: 'The results have not been verified yet.'
