何かに慣れていること (Be Used To + -ing)
be used to + -ing をマスターすると、「現在の習慣」や「慣れていること」、「自然な感覚」を英語で伝える時に、とってもネイティブらしく聞こえるよ!」
Grammar Rule in 30 Seconds
Use 'be used to' + '-ing' to describe things that are familiar, normal, or no longer strange to you.
- Always include the verb 'be' (am/is/are/was) before 'used to' for current familiarity. Example: 'I am used to the noise.'
- Follow 'used to' with a noun or a gerund (-ing verb). Example: 'She is used to driving in traffic.'
- Never use the base form of the verb after 'be used to'. Example: 'I am used to wake up early' is incorrect.
Overview
be used to だよ。これは「これ、変だな」から「これがいつもの生活だ」への架け橋なんだ。多くの人がこれを過去の{習慣|しゅう|かん}とごっちゃにして間違えちゃうんだけど、今日は二度とそのミスをしないようにしっかりマスターしていこうね。used to (慣れている)んだ。英語では、何かがもう新しくも、変でも、難しくもないことを示すためにこのパターンを使うよ。これは「動作」ではなくて「状態」なんだ。何かを「している」わけじゃなくて、その状況に「{居心地|い|ごこ|ち}がいい」ってこと。過去のことを話す used to と違って、 be used to は過去、現在、そして未来でも使えるんだ。日常のテキストやカジュアルなチャットでもめちゃくちゃよく使われるよ。もし君が大学生活をなんとかサバイブしているなら、きっと4時間{睡眠|すい|みん}と冷めたピザで生き延びることにすでに used to なはず。まさにそういう話なんだ。How This Grammar Works
to は「前置詞」だってこと。不定詞の一部じゃないんだ。これが多くの学習者にとって「なるほど!」となる瞬間だよ。 to が前置詞だから、その後ろには必ず「名詞」か「動名詞(-ing形)」が来る。動詞の{原形|げん|けい}を置いちゃダメなんだ。「excited about(〜にワクワクしている)」というフレーズと同じように考えてみて。「I am excited about the party(パーティーにワクワクしている)」とか「I am excited about going(行くことにワクワクしている)」とは言うけど、「I am excited about go」とは言わないよね。それと同じロジックがここでも当てはまるんだ。君は何かに used to している。その「何か」が名詞や動名詞になるわけ。それが君の今の現実を表すんだ。もし毎晩夜中の2時までTikTokをスクロールしちゃってるなら、君は夜遅くまでスクロールすることに used to なんだ。それが君の習慣で、今ではそれが普通に感じられるってことだね。もし友達が賑やかな都会の騒音について文句を言っているとして、でも君がニューヨーク育ちなら、「I am used to the noise(騒音には慣れてるよ)」って言うかもしれない。もう気にならないし、ただの生活の一部になってるからね。Formation Pattern
to be の適切な形を加えよう。これは主語や話している時間(現在・過去・未来)によって変わるよ (am, is, are, was, were, will be)。
used to を入れる。

- **Informal(インフォーマル)
** 'I'm used to the lag on this server.' (このサーバーのラグには慣れてるよ。— 友人や同僚との標準的な会話)。

When To Use It
- 新しい環境: 寮に引っ越して、ようやく5人の知らない人とバスルームを{共有|きょう|ゆう}することに
used toなった。 - テクノロジー: 新しいゲーミングマウスを買って、追加のボタンに
used toなった。 - 天気: フロリダからカナダに引っ越して、ようやく服を3枚重ね着することに
used toなった。 - 仕事・勉強: 3週間講義を受けた後、教授の変ななまりに
used toなった。 - ソーシャルメディア: 何かの製品を口に出した途端にターゲット広告が出てくることに
used toなった。(ちょっと不気味だよね?)
Memory Trick
used という言葉を、 Adjusted(調整された・適応した) という言葉に置き換えて{想像|そう|ぞう}してみて。
'I am Adjusted To waking up early.'(私は早起きすることに「適応して」いる)
もし 'Adjusted To' が文の中でしっくりくるなら、 -ing 形を使おう!もし過去の習慣('I used to play soccer' 昔はサッカーをしていた、など)について話しているなら、 'Adjusted To' は意味不明に聞こえるはず。「サッカーをするために適応した」?いや、おかしいよね。そうすれば、それが別のルールだって見分けられるよ。
Common Mistakes
- 1'be' 動詞を忘れる: 「I used to the city.」と言っちゃう人がいるけど、これは間違い!
am/is/areが必要だよ。正解は: 「I am used to the city.」 - 2不定詞を使う: これが一番大きなミス。 「I am used to wake up early.」と言っちゃうと、英語の先生が気絶しちゃうよ。
-ingを使おう!正解は: 「I am used to waking up early.」 - 3'be used to' と 'used to' を混同する: 忘れないで、
used to + infinitiveは「昔はしていたけど今はしていないこと」のため。Be used to + -ingは「今、自分にとって普通のこと」のために使うんだ。 - 4'use to' と綴る: 肯定文では、常に 'd' が付いた
usedだよ。早口で話すと 'd' が聞き取りにくくても、書く時は必ず入れなきゃダメだよ。
Contrast With Similar Patterns

`be`動詞を見つけよう
used to の前に必ず am, is, are, was, were, will be などの be動詞があるかチェックしてね。もし be動詞がなければ、それは「昔は~だった」という過去の習慣 (used to + infinitive) の話だよ。「I used to live in Tokyo.」動名詞がカギだよ!
be used to の to は前置詞だから、その後には必ず動詞の -ing 形(動名詞)が来るんだ。動詞の原形は使わないでね。「I am used to studying abroad.」「自分にとって普通」を考えよう
be used to + -ing を使うかどうか迷ったら、「それは今の自分にとって普通で、心地よいこと?」と考えてみて。もしそうなら、このパターンでOKだよ!「It's normal for me to drink coffee daily.」新しい文化に慣れる時
名詞も使えるよ!
be used to の後には、動名詞だけじゃなくて名詞や名詞句も使えることを忘れないでね。「I'm used to the traffic.」(交通渋滞には慣れている)のように、「I'm used to driving in traffic.」(交通渋滞の中で運転することに慣れている)の代わりに使えるんだ。Smart Tips
Check if there is a 'be' verb before 'used'. If yes, add -ing!
Use 'get used to' to describe your journey of adjustment.
Use 'accustomed to' instead of 'used to' for a more professional tone.
Use the present perfect: 'I still haven't gotten used to...'
発音
The 'd' in 'used'
In 'used to', the 'd' is often silent or blends into the 't' of 'to'. It sounds like /juːst tuː/.
The 's' sound
The 's' in 'used to' is unvoiced /s/, unlike the verb 'to use' which has a voiced /z/.
Stress on 'used'
I am USED to it.
Emphasizing that you are indeed familiar, perhaps after someone doubted you.
暗記しよう
記憶術
Remember: 'BE used to -ING'. If you see the verb 'BE', you must use the '-ING'.
視覚的連想
Imagine a person standing comfortably in a snowstorm. They are wearing a t-shirt and smiling. They are 'used to' the cold. The 'BE' verb is like the t-shirt—it's part of their current state.
Rhyme
With a 'be' and a 'to', the '-ing' is for you!

The word 'used' comes from the Old French 'user', meaning 'to practice or be accustomed to'.

よくある質問 (8)
`Used to` describes a past habit (e.g., 'I used to smoke'). `Be used to` describes current familiarity (e.g., 'I am used to the noise').
No. You must say `I am used to swimming`. The 'to' is a preposition, so it needs a gerund.
Not exactly. `Get used to` is the process of becoming familiar. `Be used to` is the final state of being familiar.
Yes! 'You will soon be used to the new system.'
Because 'used' is acting as an adjective (like 'tired' or 'bored').
Yes, absolutely. 'I am used to the city.'
It is neutral and used in all contexts, from casual chat to business meetings.
Use the negative: 'I am not used to...' or 'I haven't gotten used to...'
