flexing
曲がる
解説 Definition
flexing は flex(曲げる、曲がる)の現在分詞・動名詞です。物や体の一部がしなるように曲がる動きを表し、筋肉を見せびらかす意味とは区別して使います。
Flexing is the action or process of bending repeatedly or moving into a curved position, especially when a body part, structure, or material responds to force without immediately breaking.
覚え方のコツ Memory Tip
flex「曲げる・しなる」に -ing をそのまま加えた動名詞で、綴りは flexing、発音は /ˈfleksɪŋ/ です。語末の /ks/ の後に /ɪŋ/ が続きます。flexing of a branch や bridge のように、力を受けて物が曲がる動きを指し、筋肉を誇示する口語用法とは文脈で区別します。
Start with flex, “to bend,” and add -ing without any spelling change: flex becomes flexing, pronounced /ˈfleksɪŋ/. Here the gerund names the physical movement or process of bending. Picture the flexing of a branch in strong wind, a bridge under traffic, or a thin sheet of metal under repeated pressure. These combinations keep the target sense clear. In informal contexts flexing can mean displaying muscles or showing off, but the examples here concern an object or body part bending under force.
例文

枝がゆっくり曲がる様子から、風の強さがわかりました。
Repeated flexing can damage this thin piece of metal.
何度も曲がると、この薄い金属片は傷むことがあります。
The engineer measured the flexing of the bridge under heavy traffic.

flexing の語源・成り立ち Etymology
ラテン語の「flectere(曲げる)」の過去分詞形「flexus」に由来します。語根「flex-」が「曲がる」を意味し、動名詞化の「-ing」が付きました。「flexible(柔軟な)」や「deflect(そらす)」と同源で、関節や物体が自在にしなる様子が意味の核心です。
Flexing is the -ing form of flex. The verb flex comes through Latin flexus, the past participle of flectere, “to bend.” The element flex- therefore carries the central idea of bending or turning. It also appears in flexible, describing something capable of bending, and is historically related to words such as deflect. Adding -ing creates a participle or gerund referring to the continuing action or process of bending.
