チューブ
解説 Definition
tube はチューブ、管という意味です。日本語の「チューブ」と同じく細長い容器や管を指しますが、英語では地下鉄を指す場合もあります。
A tube is a long, hollow, usually cylindrical object through which liquids, gases, or other materials can pass, or a squeezable cylindrical container for substances such as toothpaste. In British usage, the Tube also refers informally to the London Underground.
覚え方のコツ Memory Tip
日本語の「チューブ」より範囲が広く、中空の細長い管と、歯磨き粉などを入れる押し出し容器の両方を表します。a tube of toothpaste、water flows through a tube という定番表現で覚えましょう。ロンドン地下鉄は筒状のトンネルから the Tube と大文字で呼ばれます。
Think of one basic shape: a long hollow cylinder. That image covers a medical tube, a pipe-like tube carrying water, and a squeezable tube containing toothpaste or cream. Learn the common pattern a tube of toothpaste, where tube names the container rather than its contents. English tube is broader than the Japanese loanword may suggest, since it can describe many hollow cylindrical objects. In Britain, the Tube, with a capital T, is the familiar name for the London Underground, an extension based on the tube-like form of its tunnels.
例文

tube の語源・成り立ち Etymology
ラテン語 tubus（管、筒）に由来し、フランス語 tube を経て英語に入った。中が空洞の円筒形を指す基本語。関連語: tuba（管状の楽器）、tubular（管状の）。地下鉄を the Tube と呼ぶのもトンネルの筒状の形から。
Tube entered English through French tube and derives from Latin tubus, meaning a pipe or tube. Its central meaning has remained a hollow cylindrical object. Related formations include tubular, “shaped like a tube,” and tubule, “a very small tube.” The informal British name the Tube for the London Underground developed from the cylindrical tunnels used by its deep-level railway lines, preserving the same basic image of a hollow passage.
