い形容詞が表すこと\n\nまず、身近（みぢか）ない形容詞を意味（いみ）といっしょに覚（おぼ）えましょう。\n\n| 表すこと | い形容詞 | 例 |\n| --- | --- | --- |\n| 大きさ | **大きい・小（ちい）さい** | 大きい犬（いぬ） |\n| 新しさ | **新（あたら）しい・古（ふる）い** | 新しい本（ほん） |\n| 味 | **おいしい・甘（あま）い** | 甘いケーキ |\n| 感想（かんそう） | **楽（たの）しい・面白（おもしろ）い** | 面白い映画（えいが） |\n\n- 目（め）で分かる特徴には、**白（しろ）い**や**長（なが）い**が使えます。\n- 食べ物の味には、**辛（から）い**や**おいしい**が使えます。\n- 自分（じぶん）の感想には、**楽しい**や**難（むずか）しい**が使えます。\n\n## 名詞の前に置く形\n\nい形容詞を名詞の前に置くときは、語尾（ごび）の「い」をそのまま残（のこ）します。\n\n**い形容詞＋名詞**\n\n:::example\n- **安（やす）い店（みせ）**でパンを買（か）います。\n- **青（あお）い傘（かさ）**です。\n- **寒（さむ）い朝（あさ）**にコーヒーを飲（の）みます。\n:::\n\n「い」と名詞の間（あいだ）に「な」や「です」は入りません。\n\n:::warning\n- ✓ **高（たか）い山（やま）**\n- ✗ **高いな山**\n- ✗ **高いです山**\n:::\n\n## 文末で使う形\n\n文末（ぶんまつ）では、い形容詞のあとに「です」を添（そ）えると丁寧（ていねい）です。\n\n| 話題（わだい） | い形容詞 | 丁寧な文 |\n| --- | --- | --- |\n| この部屋（へや） | 広（ひろ）い | この部屋は**広いです**。 |\n| 日本語（にほんご） | 面白い | 日本語は**面白いです**。 |\n| きょう | 暑（あつ）い | きょうは**暑いです**。 |\n\n:::note\n「です」は丁寧さを加（くわ）えます。い形容詞の「い」は消（け）しません。\n:::\n\n## な形容詞と見分ける\n\n「い」で終わることばでも、すべてがい形容詞ではありません。**きれい**と**嫌（きら）い**は、な形容詞です。\n\n| 種類（しゅるい） | 名詞の前 | 文末 |\n| --- | --- | --- |\n| い形容詞 | **新しい町（まち）** | 町は**新しいです**。 |\n| な形容詞 | **きれいな町** | 町は**きれいです**。 |\n\n:::tip\n辞書（じしょ）や単語帳（たんごちょう）で、ことばと種類をいっしょに覚えましょう。「い」で終わるかどうかだけでは決（き）めません。\n:::\n\n## 文を作る手順\n\n1. 説明したい物や人を決めます。\n2. その特徴に合うい形容詞を選（えら）びます。\n3. 名詞の前なら「い」を残してそのまま置（お）きます。\n4. 文末なら「い形容詞です」で丁寧に伝えます。\n\n:::example\n**伝えたいこと：**駅（えき）の近（ちか）くにある店は小さくて、料理（りょうり）がおいしいです。\n\n**名詞の前：**小さい店\n\n**文末：**この店の料理はおいしいです。\n:::\n\n## 覚えておくこと\n\n| 場所（ばしょ） | 形 | 例 |\n| --- | --- | --- |\n| 名詞の前 | **い形容詞＋名詞** | かわいい猫（ねこ） |\n| 文末 | **い形容詞＋です** | この猫はかわいいです。 |\n\nい形容詞の「い」を残すこと、名詞の前に「な」を入れないことを確（たし）かめると、自然（しぜん）な文になります。","ja","A1",36,[13],{"id":14,"name":15,"level":10,"language":9,"isCompleted":16,"completionPercentage":17,"totalExercises":18,"completedExercises":17},"01a09c0e-9724-714c-b10c-51a628487029","い形容詞とな形容詞の基本",false,0,8,"2026-09-13T11:16:47+00:00","2026-10-11T12:53:35+00:00",[22],{"id":23,"title":24,"vocabularyListWords":25,"isPublished":36},"01a09a7c-76bb-76ca-a9df-d9c9dad8e39e","い形容詞の基本の語彙",[26,39,50,62,73,84,95,106,116,127,137,146,157,169,178,189,200,211,222,233,244,255],{"id":27,"vocabularyWord":28,"displayOrder":37},"01a09a7c-76bb-772e-a9df-d9c9db0e9054",{"id":29,"word":30,"frequency":18,"level":10,"language":9,"audioFilePath":31,"partsOfSpeech":32,"audio":36,"audioUrl":38},"01a09a7c-285f-714b-8f41-0c552cd952cb","おいしい","tts_5920de9d7b041467_ja-JP.mp3",[33],{"id":34,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-288c-70f4-9c8c-4cab29a9436d","ADJECTIVE",true,1,"\u002Fuploads\u002Faudio\u002Ftts_5920de9d7b041467_ja-JP.mp3",{"id":40,"vocabularyWord":41,"displayOrder":49},"01a09a7c-76bb-7766-a9df-d9c9db7f09c0",{"id":42,"word":43,"frequency":18,"level":10,"language":9,"audioFilePath":44,"partsOfSpeech":45,"audio":36,"audioUrl":48},"01a09a7c-2997-7825-9d31-3d3ffc13da11","甘い","tts_fb7cec10a797fef4_ja-JP.mp3",[46],{"id":47,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-29a1-759c-8eb5-2228cfc994d2","\u002Fuploads\u002Faudio\u002Ftts_fb7cec10a797fef4_ja-JP.mp3",2,{"id":51,"vocabularyWord":52,"displayOrder":61},"01a09a7c-76bb-778a-a9df-d9c9dc5f4fc4",{"id":53,"word":54,"frequency":55,"level":10,"language":9,"audioFilePath":56,"partsOfSpeech":57,"audio":36,"audioUrl":60},"01a09a7c-29e2-77f8-902b-b7c2237bbdc4","大きい",10,"tts_ae759e8e13026ab4_ja-JP.mp3",[58],{"id":59,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-2a2a-7d6f-bac5-3c638d4b9a22","\u002Fuploads\u002Faudio\u002Ftts_ae759e8e13026ab4_ja-JP.mp3",3,{"id":63,"vocabularyWord":64,"displayOrder":72},"01a09a7c-76bb-77aa-a9df-d9c9dceeaba5",{"id":65,"word":66,"frequency":55,"level":10,"language":9,"audioFilePath":67,"partsOfSpeech":68,"audio":36,"audioUrl":71},"01a09a7c-2879-7632-88a0-404656fd9af9","小さい","tts_8e069448369f5044_ja-JP.mp3",[69],{"id":70,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-288e-7954-a62e-5aefd0420159","\u002Fuploads\u002Faudio\u002Ftts_8e069448369f5044_ja-JP.mp3",4,{"id":74,"vocabularyWord":75,"displayOrder":83},"01a09a7c-76bb-77ca-a9df-d9c9dd439334",{"id":76,"word":77,"frequency":18,"level":10,"language":9,"audioFilePath":78,"partsOfSpeech":79,"audio":36,"audioUrl":82},"01a09a7c-279f-72e6-b002-e27523b3e2a4","新しい","tts_a0a1626aaeb94bbf_ja-JP.mp3",[80],{"id":81,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-27ea-7125-84cf-757da7675658","\u002Fuploads\u002Faudio\u002Ftts_a0a1626aaeb94bbf_ja-JP.mp3",5,{"id":85,"vocabularyWord":86,"displayOrder":94},"01a09a7c-76bb-77e6-a9df-d9c9ddf24004",{"id":87,"word":88,"frequency":18,"level":10,"language":9,"audioFilePath":89,"partsOfSpeech":90,"audio":36,"audioUrl":93},"01a09a7c-2856-79b8-b398-e7924de5785e","古い","tts_55bf8d314c779474_ja-JP.mp3",[91],{"id":92,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-288b-71dc-bad0-16896904c7b9","\u002Fuploads\u002Faudio\u002Ftts_55bf8d314c779474_ja-JP.mp3",6,{"id":96,"vocabularyWord":97,"displayOrder":105},"01a09a7c-76bb-7806-a9df-d9c9dea447d7",{"id":98,"word":99,"frequency":18,"level":10,"language":9,"audioFilePath":100,"partsOfSpeech":101,"audio":36,"audioUrl":104},"01a09a7c-2876-7495-86e5-f0c47ed5c491","安い","tts_6cee33a0a5f30787_ja-JP.mp3",[102],{"id":103,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-288e-74f4-a62e-5aefce33cd31","\u002Fuploads\u002Faudio\u002Ftts_6cee33a0a5f30787_ja-JP.mp3",7,{"id":107,"vocabularyWord":108,"displayOrder":18},"01a09a7c-76bb-7822-a9df-d9c9df5fc886",{"id":109,"word":110,"frequency":18,"level":10,"language":9,"audioFilePath":111,"partsOfSpeech":112,"audio":36,"audioUrl":115},"01a09a7c-295d-7cb5-bf93-ef2348187680","高い","tts_271e407cb492a57a_ja-JP.mp3",[113],{"id":114,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-299b-7a8d-b785-fc088cab3ca2","\u002Fuploads\u002Faudio\u002Ftts_271e407cb492a57a_ja-JP.mp3",{"id":117,"vocabularyWord":118,"displayOrder":126},"01a09a7c-76bb-783e-a9df-d9c9df7a921c",{"id":119,"word":120,"frequency":18,"level":10,"language":9,"audioFilePath":121,"partsOfSpeech":122,"audio":36,"audioUrl":125},"01a09a7c-2983-7685-a772-6100e8bf59fd","寒い","tts_270a347b9f8914c4_ja-JP.mp3",[123],{"id":124,"partOfSpeech":35,"isPrimary":36,"meaningOrder":37},"01a09a7c-299f-759c-bfba-c0c8b31d2209","\u002Fuploads\u002Faudio\u002Ftts_270a347b9f8914c4_ja-JP.mp3",9,{"id":128,"vocabularyWord":129,"displayOrder":55},"01a09a7c-76bb-785a-a9df-d9c9e01fbb89",{"id":130,"word":131,"frequency":18,"level":10,"language":9,"audioFilePath":132,"partsOfSpeech":133,"audio":36,"audioUrl":136},"01a09a7c-286d-72ed-9cce-6df8b29fc079","暑い","tts_a12c301c61ece30e_ja-JP.mp3",[134],{"id":135,"part
