elongate
伸びる
解説 Definition
elongate は原形の動詞で、「伸びる」「長くなる」、または「長くする」という意味です。category は活用形扱いですが、英語ではそのまま基本形として使われます。
To elongate is to become longer, especially by stretching or growing lengthwise. It can describe cells, muscles, fibers, or other objects whose length increases.
覚え方のコツ Memory Tip
elongate は「長い」の long を含み、e-＋long＋-ate で「長くなる・長くする」と捉えます。例文の cells、muscles、fibers のように、細長いものがさらに伸びる場面と結び付けましょう。活用形という分類でも、実際には原形で、動詞の発音は語末が /eɪt/ です。
Connect elongate with the familiar word long: something that elongates becomes longer. Picture plant cells lengthening as a stem grows, muscles gradually extending during a stretch, or fibers becoming longer when pulled. These typical subjects help distinguish elongate from grow, which can mean increasing in any dimension. Although this entry is categorized as an inflected form, elongate itself is the base verb. As a verb, its final element is pronounced like “ate,” /eɪt/.
例文
Some cells elongate as the plant grows.
植物が成長するにつれて、一部の細胞は伸びます。
The muscles elongate slowly during the stretch.
ストレッチ中に筋肉はゆっくり伸びます。
These fibers elongate when they are pulled gently.
これらの繊維はやさしく引っ張ると伸びます。

elongate の語源・成り立ち Etymology
ラテン語elongare（e-「外へ」＋longus「長い」）に由来し、「長く引き伸ばす」が原義。英語のlong（長い）と同じ印欧祖語の語根*dlonghosに遡る。関連語にprolong（延長する）、longitude（経度＝長さの度合い）がある。
Elongate ultimately comes from Late Latin elongare, meaning “to make long” or “to prolong,” built from Latin ex- or e-, indicating outward movement, and longus, “long.” English long is historically related through the same ancient Indo-European word family. The structure is also visible in elongation, while prolong and longitude provide useful connections to the idea of length.
