# gē 哥 vs. gēge 哥哥
[[哥哥 is the slightly more standard or formal honorific. For example, you might use it when introducing your older brother to a third party (this is my gē). There is nothing with using it more casually, however.]][^1]
[[哥 on its own is somewhat more familiar, casual, and colloquial than 哥哥. Good for casually mentioning your older brother among peers or family.]][^2]
