解説 Definition
initiated は initiate（始める、開始する）の過去形・過去分詞です。計画、手続き、活動などが正式に始められたことを表します。
Initiated is the past tense and past participle of initiate. In passive constructions, it indicates that a planned process, project, procedure, or activity was deliberately or formally started by someone.
覚え方のコツ Memory Tip
initiated は原形 initiate の語末 e を落として -ed を付けた過去形・過去分詞です。initiate → initiated となり、語尾は /ɪd/ と一音節加えて発音します。ここでは was initiated の受け身で、計画・手続き・点検などが「正式に開始された」という意味。started より、責任者が意図的・公式に始動させた響きがあります。initial「最初の」と結び付けましょう。
Connect initiated with initiate, “to begin something deliberately,” and with initial, meaning “first.” The final silent e of initiate is dropped before -ed is added: initiate becomes initiated. Because the base ends with a t sound, the -ed ending is pronounced as an extra /ɪd/ syllable. In The project was initiated, the past participle forms a passive construction and emphasizes that someone formally set the project in motion. Compared with started, initiated often sounds more planned, official, or procedural, especially with projects, programs, checks, investigations, and reforms.

initiated の語源・成り立ち Etymology
ラテン語 initiare（始める）から。in-（中へ）+ itium（行くこと、始まり）に分解でき、「中に入って始める」が原義。関連語：initial（最初の）、initiation（入会式）。秘儀や儀式に「入門する」意味が転じて「開始する」となった。
Initiate comes from Latin initiare, “to begin” or “admit into rites,” based on initium, “beginning” or “entrance.” That noun is historically connected with the idea of going into something. The earlier ceremonial sense of admitting a person into a group or mystery developed alongside the broader sense of setting an action or process in motion. Initiated is the regular past and past-participle form, made by replacing final e with -ed.
