Questions & Answers about Sono stanco e voglio riposare.
Why does the sentence use riposare instead of a conjugated verb?
When you use a modal verb like volere (to want), the action verb that follows it stays in its original dictionary form, called the infinitive. Since voglio already tells us who is doing the action (I want), riposare (to rest) does not need to change its ending.
Why doesn't this sentence start with io?
In Italian, you usually drop subject pronouns like io (I) because the verb itself tells you who is doing the action. Both sono (I am) and voglio (I want) are the specific forms used for I, so the subject is already perfectly clear without adding io.
