‘叨扰’ (dāo rǎo) is a modest, self-deprecating verb used to acknowledge that one has imposed on someone’s time, hospitality, or resources. Literally, 叨 (dāo) means ‘to chatter’ or ‘to nibble’ — historically evoking the image of repeatedly taking small bites, while 扰 (rǎo) means ‘to disturb’ or ‘to trouble’. Together, they convey the sense of ‘lightly but repeatedly troubling’ — softened by humility and social grace. It is never used to describe serious harm or offense, but rather everyday inconveniences like staying as a guest, asking for help, or receiving favors.

This expression belongs to formal or semi-formal register and appears frequently in spoken and written Chinese when expressing gratitude mixed with apology — especially upon leaving someone’s home, after receiving assistance, or at the end of an email or message. It reflects Confucian values of humility and reciprocity: by naming your own imposition, you affirm respect for the other person’s kindness and effort.
