覚え方のコツ Memory Tip
extending は extend にそのまま -ing を付けた現在分詞・動名詞で、発音は /ɪkˈstendɪŋ/ です。ex-「外へ」＋「伸ばす」の像を持ち、extend the meeting、deadline、service のように、時間・期限・提供範囲を今より先へ伸ばす場面で覚えます。
Extending is the -ing form of extend, made by adding -ing without changing the base spelling. It is pronounced /ɪkˈstendɪŋ/. Keep the literal image of stretching something outward: the historical parts convey “out” and “stretch.” That image works for several common objects. Extending a meeting or deadline moves its endpoint later; extending a road makes it reach farther; extending a service makes it available to more places or people. Learn the word with these objects so that both the time and range senses feel like versions of the same outward movement.
例文

The school is extending the deadline.
学校は締め切りを延長しています。
The company is extending the service to more cities.
その会社はサービスをより多くの都市へ広げています。

extending の語源・成り立ち Etymology
ラテン語 extendere（ex-「外へ」+ tendere「伸ばす」）が語源。フランス語経由で英語に入った。tend（向かう）やtension（緊張）も同じ語根を持つ。「外へ引き伸ばす」が原義で、時間・範囲・期限などを広げる意味に発展した。
Extending is formed by adding -ing to extend. Extend entered English through French from Latin extendere, composed of ex-, “out,” and tendere, “to stretch.” Its literal historical image is therefore stretching something outward. English generalized that physical idea to duration, deadlines, territory, services, and other kinds of range. Tend, tension, and extent are historically related through the Latin root associated with stretching or directing.
