The word "派对" (pàiduì) is formed through a process of phonetic borrowing from the English word "party". It is a direct transliteration, where the two Chinese characters were selected not for their individual meanings (which are "to send" and "to pair/team" respectively), but specifically because their combined pronunciation closely approximates the sound of the English source word. This created a new, standalone term in Chinese that carries the social meaning of a festive gathering.
