What is rebracketing in linguistics? (5)(Italian)

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 Italian:

Un’arma:

Original form: “una arma” (meaning “a weapon”)

Rebracketed form: “un’arma,” where “un” is the indefinite article in Italian.

L’anello:

Original form: “lo anello” (meaning “the ring”)

Rebracketed form: “l’anello,” where “l’” is now the article and “anello” the noun.
