rounded
丸い
解説 Definition
rounded は round（丸い、丸くする）に由来する形で、丸みのある、角が丸いという意味です。完全な円だけでなく、角や形がなめらかに丸いことにも使います。
Rounded describes something whose outline, surface, corners, or other features curve smoothly rather than forming sharp angles. It can refer to an overall curved shape or to particular parts, such as a chair back or the corners of a table.
覚え方のコツ Memory Tip
rounded は round に -ed が付いて「丸みを帯びた状態」を表す形容詞です。語末 /d/ の後の -ed は /ɪd/ と一音節増え、/ˈraʊndɪd/。rounded corners、a rounded back、smooth and rounded のように、完全な円ではなく角や輪郭がなめらかに丸い物を思い浮かべましょう。
Build rounded from round plus -ed: the ending presents something as having acquired or possessing a round shape. Since round ends in /d/, -ed is pronounced /ɪd/, adding a syllable: /ˈraʊndɪd/. Do not limit the image to a perfect circle. A table can have rounded corners, a chair can have a rounded back, and river stones can become smooth and rounded. The useful contrast is with sharp, square, or angular. Picture hard corners gradually being worn away until the outline curves smoothly.

rounded の語源・成り立ち Etymology
rounded は round に状態を表す -ed が付いた語です。round は古フランス語 rond を経てラテン語 rotundus「車輪のように丸い」にさかのぼり、rotary や rotund も同系です。つまり「丸さを帯びた」がそのまま意味になっています。
Rounded is derived from round with the state-forming suffix -ed. Round entered English through Old French rond and ultimately goes back to Latin rotundus, meaning “round” or “wheel-shaped.” The Latin form is also reflected in rotund, while words such as rotary share the broader historical association with turning or wheels. The adjective rounded therefore transparently describes something that has been made round or has acquired noticeable curves.
