覚え方のコツ Memory Tip
protruding は原形 protrude の語末 e を落として -ing を付けた形で、ここでは形容詞的に「突き出ている」。pro-「前へ・外へ」＋「押す」に由来する語根を意識し、a protruding nail／rock／balcony のように、周囲の面より外へ出て危険・目立つ物と結びつけて覚えましょう。
Connect protruding with its base verb protrude. Before adding -ing, the final e is dropped: protrude becomes protruding. The prefix pro- suggests movement forward or outward, while the historical root carries the idea of pushing. Imagine a nail pushed partly through a floor so that one end remains outside the surface. Common combinations include “a protruding nail,” “a protruding rock,” and “a protruding balcony.” Unlike merely visible, protruding specifically means extending beyond the surrounding line or surface, often making the object noticeable or hazardous.

protruding の語源・成り立ち Etymology
ラテン語の接頭辞pro-（外へ・前方へ）＋動詞trudere（押す）に由来し、「外へ強く押し出す」が原義です。これに状態を示す-ingが付き、物体が基準面から突き出た様子を表します。同語根にintrude（割り込む）やextrude（押し出す）があり、「押す」のイメージから「突き出ている」状態が直感的に理解できます。
Protruding is the -ing form of protrude, with the final e of protrude removed before the suffix is added. Protrude comes from Latin protrudere, built from pro-, “forward” or “outward,” and trudere, “to thrust or push.” The literal notion is therefore of something pushed outward. Related formations include intrude, involving movement into a space, and extrude, meaning to force or shape material outward through an opening.
