咱俩 (zán liǎ) is an informal, inclusive first-person plural pronoun meaning 'you and I' or 'we' — specifically referring to exactly two people: the speaker and the listener. It combines 咱 (zán), a colloquial variant of 'we' (including the listener), and 俩 (liǎ), a measure word meaning 'two', attached directly to a pronoun or noun to indicate 'two of [X]'. Unlike formal 我们 (wǒmen), which can include others beyond the two speakers, 咱俩 explicitly excludes third parties and conveys closeness, familiarity, and shared experience.

This term is widely used in spoken Mandarin across northern and central China, especially in casual conversations among friends, family members, or close colleagues. It’s rarely found in formal writing or official speech. Because it implies intimacy and equality, using 咱俩 with strangers or superiors may sound overly familiar or inappropriate — context and relationship matter greatly. It cannot be used with verbs requiring object markers like 把 or passive constructions, and it never takes possessive 的 (e.g., *咱俩的 is possible only when indicating joint possession, not as a standalone pronoun form).
