覚え方のコツ Memory Tip
原形 decide の語末の無音 e を落として -ing を付け、deciding となる。be deciding where/which ～ は選択肢を検討して「決めているところ」、Deciding early なら「早く決めること」。decision は名詞なので、動作を表す deciding と区別する。
Deciding comes from decide by dropping the final silent e before adding -ing: decide becomes deciding. Use it in a progressive form when the choice is currently being considered, as in “We are deciding where to eat.” As a gerund, it names the action, as in “Deciding early helped us.” Remember useful patterns such as decide where to go, decide which one to buy, and decide whether to act. Keep it distinct from decision, the countable noun for the conclusion or choice that results.

deciding の語源・成り立ち Etymology
deciding は decide から。古フランス語経由でラテン語 decidere「切り離す」に由来します。de-「離して」+ caedere「切る」で、迷いを断ち切って結論を出す感覚です。関連語は precise, incision。
Deciding is the -ing form of decide, made by dropping the final silent e before adding -ing. Decide entered English through French from Latin decidere, literally “to cut off,” formed from de-, expressing separation, and caedere, “to cut.” The image developed into ending uncertainty by settling a question. In modern English, deciding functions either as a present participle in a verb phrase or as a gerund.
