What does the "se" rule mean? You can't use two "L" pronouns in a row, so you change the first pronoun to "se".

You "say" the pronouns aloud 3 times.

You use "se" to describe actions you do to yourself or others.

You use "se" instead of all other pronouns.

The most common use of se is a reflexive pronoun. Such pronouns indicate that the subject of a verb is also its object. In English, this is usually accomplished by using verbs such as "himself" or "themselves." Se is used as the reflexive pronoun for third-person uses (including when usted or ustedes is the subject).

Explanation: The word "se" has many uses in Spanish. Two of the most frequent uses are the impersonal "se" and the passive "se". The impersonal "se" is used with a third person singular verb to express the impersonal English subjects, one, you, people, or they.
