interdepartmental
部門間の

Interdepartmental means involving two or more departments within the same organization. It is commonly used in business, government, and education when different sections need to communicate, cooperate, or share responsibility.
覚え方のコツ Memory Tip
inter- が「〜の間」（international, interpersonal と同じ）、-al が形容詞化だと押さえると、department をはさんで「部門と部門の間の」という形がそのまま見える。会議・連携・対立の文脈で出やすく、an interdepartmental meeting / project / dispute のまとまりで覚えると定着しやすい。departmental だけなら「部門の／部門内の」、internal なら「組織内部の」なので、比較して覚えると混同しにくい。
Break it into parts: "inter-" means between, "department" is the middle, and "-al" makes it an adjective. So the word literally means "between departments." It is easy to remember in common office phrases like "interdepartmental meeting" or "interdepartmental project."

interdepartmental の類義語・関連語
interdepartmental の語源・成り立ち Etymology
interdepartmental は inter-『間で』+ department + -al。department は古フランス語経由でラテン語 partire『分ける』にさかのぼるため、全体で『分けられた部門の間の』という構図が見える。関連語は depart, partition。
Interdepartmental is made from `inter-` meaning "between," `department`, and the adjective ending `-al`. `Department` came through French from roots related to dividing or separating, ultimately from Latin `partire`, "to divide." So the word originally meant something happening "between separated divisions" or sections. Related words include `depart`, `part`, and `partition`.
