司式した
解説 Definition
officiated は officiate（司式する、公式に執り行う）の過去形・過去分詞です。結婚式や儀式などで、正式な役割を持つ人が式を進行したことを表します。
The past tense and past participle of officiate, meaning formally conducted a wedding, religious service, ceremony, or similar event while acting in an authorized role.
覚え方のコツ Memory Tip
原形 officiate に -d を付けた過去形・過去分詞で、語末は /ɪd/ と一音節加えて発音します。office・official と同じく「公的な役目」が核です。officiated at the wedding／ceremony なら、正式な立場で結婚式や儀式を進行したこと。単なる司会より、権限を持って式を執り行う点を意識しましょう。
Connect officiated with office and official: all involve an assigned or recognized duty. It is the past-tense and past-participle form of officiate, made by adding -d because the base already ends in e. The ending is pronounced /ɪd/, adding another syllable. In officiated at a wedding or ceremony, picture an authorized judge, minister, or other official formally conducting the event. This is more specific than merely hosting or introducing speakers, because the person performs the recognized duties that make the ceremony official.

officiated の語源・成り立ち Etymology
officiated は officiate の過去形で、ラテン語 officium「務め・公的な役目」から来た中世ラテン語 officiare に由来する。原義は「定められた務めを果たす」で、office や official と同根だから、式や試合で公式の役を務める→「司式した」と理解できる。
Officiated is the past-tense and past-participle form of officiate. Officiate entered English through Medieval Latin forms related to officiare, “to perform a duty,” ultimately based on Latin officium, meaning “service, duty, or official function.” Office and official belong to the same word family. The sense developed naturally from carrying out an assigned office to performing the formal duties required at a ceremony, religious service, wedding, or sporting event.
