覚え方のコツ Memory Tip
demonstrate の語末の e を落として -ing を付けた現在分詞・動名詞で、demonstrating と綴る。demonstrating how to use a camera のように、説明だけでなく実際に見せる場面を思い浮かべる。showing より「方法・機能を明確に示す」意識が強く、ここでは抗議活動の意味ではない。
Demonstrating is formed by dropping the final e of demonstrate and adding -ing. Link it with a teacher performing an experiment or a colleague showing how to use an app. The key idea is not merely talking about a method but making it clear by actually showing the steps or operation. Showing is a broader word, while demonstrating often suggests an instructive, organized display for an audience. Demonstrate can also mean proving a fact or taking part in a public protest, but the examples here specifically concern practical instruction through visible performance.

demonstrating の語源・成り立ち Etymology
ラテン語 demonstrare（de-「完全に」+ monstrare「示す」）の現在分詞形。「はっきりと指し示す」が原義。関連語: demonstration（実演）、monster（monstrare と同根で「神が示すもの＝怪物」）。論理的に証明する意味も「目に見える形で示す」という語根から派生した。
Demonstrating is the -ing form of demonstrate. Demonstrate comes through Latin demonstrāre, “to point out or show clearly,” formed from de-, used intensively, and monstrāre, “to show.” The latter is related to Latin monstrum, something regarded as a sign or portent, from which monster eventually developed. In English, the final e of demonstrate is dropped before -ing. The instructional sense retains the central idea of making something clearly visible.
