对话 (duìhuà) is chiefly a noun meaning 'dialogue' or 'conversation' — an exchange of words between two or more parties — and also functions as a verb 'to hold talks / to talk with.'
It combines 对 ('facing / mutual') and 话 ('speech / words'), literally 'facing-speech.' It is neutral in register, appearing in textbook dialogues, film scripts, and, importantly, in political and diplomatic contexts (中美对话 'China–US talks').
Two differences from English: 对话 as a noun emphasizes a structured, back-and-forth exchange, so a casual chat is more often 聊天 (liáotiān), while 对话 sounds slightly more formal or purposeful; and as a verb it often implies negotiation or dialogue between sides/institutions (与……对话 'to have a dialogue with'), not just chatting. Language learners meet it constantly as the label for practice conversations.
