よくある質問
初心者にとって最も重要な英語ワードリストは何ですか？
絶対初心者には、英語の最頻出1,000語リストが最も重要です。研究によると、この1,000語が日常会話の語彙の約80%をカバーしています。これを習得したら、約90%の一般英語テキストをカバーするNGSL（2,800語）に進みましょう。Oxford 3000も頻度と有用性の両方で単語を選んでいるため、総合的なコミュニケーション能力向上の出発点として最適です。
Academic Word Listとは何ですか？誰が使うべきですか？
Academic Word List（AWL）は2000年にAveril Coxheadが編纂したもので、経済学から物理学、文学まで幅広い学術分野のテキストに頻出する570の語族を収録しています。英語で大学での学習を準備している学習者向けに設計されており、AWLを習得すると学術テキストの理解度がさらに10%向上します。IELTS 7+、TOEFL 100+、または大学レベルの英語読解を目標とするすべての学習者が体系的に取り組むべきリストです。
英語を流暢に話すには何語覚える必要がありますか？
語彙研究では次のおおよその目安が示されています：基本的なサバイバル会話に1,000語、快適な日常会話に3,000語族、未簡略化の英語テキストを辞書なしで読むには8,000〜9,000語族、ネイティブに近い読書流暢性には15,000〜20,000語族。合計数を追うより、頻度の高い単語から優先して学ぶことが大切です——頻度リストの上位にある単語ほど、1語あたりの学習効果が大きいためです。
ワードリストと語族の違いは何ですか？
ワードリストは単に、頻度・トピック・レベル順に並べた単語の集まりです。語族は1つの基本語のすべての屈折形・派生形をまとめたもので、例えば「analyse」の語族にはanalyse, analyses, analysed, analysing, analysis, analyst, analytical, analyticallyが含まれます。語彙研究では通常、語族単位で語彙サイズを測ります。なぜなら「analyse」を知っている学習者はたいていの場合、明示的に学ばなくても「analytical」を理解できるからです。
英語ワードリストを最も効果的に学ぶ方法は何ですか？
最も効果的なアプローチは、間隔反復・意味のある文脈・理解可能なインプットを組み合わせることです。Ankiなどの間隔反復ソフトを使って増加する間隔で単語を復習し、長期記憶を確保しましょう。単語は単独ではなく必ず例文の中で学んでください。そして最も重要なのは、自分のレベルに合った大量のリスニングとリーディングでリスト学習を補完することです。本物の英語コンテンツの中で自然に出会うことで、フラッシュカードだけでは得られない深い直感的な知識が形成されます。
語彙を最も速く増やす方法は理解可能なインプット——自分のレベルに合った本物の英語に何度も触れることです。
