#### Usage notes

The reflexive pronoun si is only used to refer to the third person (In English: he/she/it/they) not the first or second person (In English: I/we/you). When the subject of a sentence is first or second person, the same pronoun is repeated (with the accusative ending -n added if needed) instead of using si. (E.g. "they wash themselves" is ili lavas sin, but "I wash myself" is mi lavas min, instead of *mi lavas sin.)

##### Usage notes

* When si is part of an infinitive, it can be placed before it as a separate word, but more often it is attached to the end. In this case, the final -e of the infinitive is dropped, or, in the case of infinitives ending in -rre, the final -re is dropped. Examples: amar(e) + si = amarsi; ridur(re) + si = ridursi.
* Often translated using the passive voice in English when used as indefinite personal pronoun:
    Si dice che […] ― It is said that […]
* Verb + si is often translated as become or get + [past participle] in English.
* In cases where si (indefinite pronoun) and si (reflexive pronoun) follow each other, the first si is replaced with ci:
    Ci si lava. ― One washes oneself.
    (instead of: *Si si lava.)
* Becomes se when followed by a third-person direct object clitic (lo, la, li, le, or ne).
