What is rebracketing in linguistics? (23)(Yiddish)

Here are some examples that show how rebracketing can influence not just the forms of words but their meanings and even how new words are created in a language.

In Yiddish:

Mazl-tov:

Original form: “Mazl” (luck) + “Tov” (good)

Rebracketed form: Became “mazltov,” treated as a single expression meaning “congratulations.”

Khokhem:

Original form: “Khokhem” (wise person) + “be” (in)

Rebracketed form: Rebracketed into a single word in some dialects as “khechem.”

Rebracketing is a widespread linguistic phenomenon that can significantly influence the evolution of languages across different cultures.
