覚え方のコツ Memory Tip
collaborate「協力する」に -ed を付けた過去形・過去分詞です。語末が /t/ 音なので -ed は /ɪd/ と一音節加えて発音します。collaborated with a designer は協力相手、collaborated on a project は共同作業の対象を示します。co-「共に」＋labor「働く」の感覚で覚えましょう。
Break collaborated into the idea “worked together”: co- suggests together, and labor connects with work. It is the regular past or past-participle form of collaborate. Because collaborate ends in the /t/ sound, the -ed ending is pronounced /ɪd/, adding a syllable. Learn its prepositions as a pair: collaborate with a person or organization, but collaborate on a project, design, or event. Unlike merely helping, collaborating usually suggests that the participants contribute jointly to a shared piece of work or goal.

collaborated の語源・成り立ち Etymology
collaborated は collaborate の過去分詞形で、ラテン語 collaborare に由来します。com-「共に」+ laborare「働く」なので、「一緒に働く」がそのまま「協力する」になった語です。関連語は labor, collaboration。
Collaborated is formed by adding the regular past-tense and past-participle ending -ed to collaborate. Collaborate comes from Latin collaborare, built from com-, “with” or “together,” and laborare, “to work.” The prefix appears as col- before l, producing the literal idea of working together. English adopted collaborate in the nineteenth century. Its central cooperative sense is also visible in the related nouns collaboration and collaborator.
