Younger brother.

How it's used

While 弟 is a formal character used in compound words like 弟婦 or 賢弟, it is almost never used alone in spoken Cantonese to refer to a younger brother. Instead, the colloquial term 細佬 is the standard way to identify a younger brother in daily conversation. Using 弟 by itself in a casual setting sounds overly formal or like a line from a period drama.

Common phrases

younger brother's wife

Common mistake

Learners often try to use 弟 as a standalone noun because they see it in textbooks, but using it to address or talk about a sibling will sound unnatural to native speakers. Always use 細佬 for the person and reserve 弟 for formal written contexts or specific compound nouns.
