In Latin, the infinitive is used in several different ways. In this video, I will discuss how the infinitive can be used as the subject of a verb, in the neuter gender. This works primarily with the verb sum, esse, but there are several other verbs that regularly take an infinitive subject. And in addition, there are many instances where the infinitive doesn't appear to be a subject, as in Horace's famous quote, dulce et decorum est pro patria mori, "it is sweet and proper to die for your country."
