A respectful term for one's younger brother, often used in formal or polite contexts.
弟君はとても優秀な学生です。
My younger brother is a very excellent student.
This term is more formal than simply saying "弟" (otōto). It is often used when introducing one's younger brother to others or in formal writing.
Use "弟君" when introducing your younger brother in formal settings, such as business or academic contexts. In casual conversation, "弟" is more common.
Combination of "弟" (otōto, younger brother) and "君" (kun, a respectful suffix for males).
While "弟" is the standard term for "younger brother," "弟君" adds a layer of politeness and is often used in formal or respectful contexts.
