覚え方のコツ Memory Tip
まず単数の counterparty を核で覚える。party は日常語の「パーティー」ではなく、契約書での「当事者」。そこに counter- が付くと「向かい側の当事者」= 取引相手になる。金融では counterparty risk, exposure to counterparties, deal with multiple counterparties が頻出。複数形は party→parties と y が ies に変わる。counterpart「対応物」と似ているが、party が入ると法律・契約の相手という意味に寄る。
Focus on the singular form `counterparty` first. Here, `party` means a person or side in a contract, not a celebration, and `counter-` suggests the other side facing you. That makes it easy to link with business phrases like `counterparty risk`, and remember the plural changes from `party` to `parties`.

counterparties の語源・成り立ち Etymology
接頭辞 counter-（ラテン語 contra「反対の」）と party（古仏語 partie、ラテン語 partire「分ける」）の合成語。取引の「反対側の当事者」が原義。関連語に counterpart（対応するもの）、partition（分割）がある。金融・法律用語として定着。
"Counterparties" is formed from "counter-" and "party." "Counter-" comes from Latin "contra," meaning "opposite," and "party" came through Old French from Latin "partire," meaning "to divide." The word first meant the party on the other side, and it became a fixed term in law and finance for the other side in an agreement or transaction.
