覚え方のコツ Memory Tip
原形 commence「始まる・始める」の語末の e を取って -ing を加えた形で、-ing は /ɪŋ/ と発音します。ceremony、construction、proceedings など改まった出来事と結び付け、is commencing「開始しつつある」と覚えましょう。starting より形式張った響きがあり、公式案内や業務文書でよく使われます。
Link commencing to the base verb commence, a formal alternative to begin or start. To form it, remove the final silent e from commence and add -ing; the ending is pronounced /ɪŋ/. Imagine an announcement such as “The ceremony is commencing in the main hall.” That official setting captures the word’s tone. It also appears with construction, proceedings, operations, or a new project stage. Starting is natural in everyday conversation, while commencing often sounds ceremonial, administrative, or professional. The progressive form is commencing focuses on the beginning as it is happening or about to happen.

数か月の計画を経て、建設が始まろうとしています。

commencing の語源・成り立ち Etymology
ラテン語 com-（共に・強意）+ initiare（始める、initium＝始まりから）が語源。古フランス語 commencier を経て英語に定着した。関連語: initial（最初の）、initiate（開始する）。「物事の出発点に踏み出す」が原義。
Commence came into English through Old French commencier. The French word developed from a Late Latin formation commonly connected with com-, an intensifying element, and initiare, “to begin,” from initium, “beginning.” Its long history in legal, ceremonial, and administrative language helps explain its formal tone today. Commencing is formed regularly by dropping the final silent e of commence before adding -ing.
