Grammatical Overview
Can is one of the most high-frequency modal auxiliary verbs in the English language. It primarily functions to express physical or mental ability, general possibility, or to request and grant permission. Because it is a modal, it does not take an -s in the third-person singular and is always followed by a bare infinitive in its active base form. In conversation, it often acts as a structural driver for polite requests (Can I...) or spontaneous offers of help (I can...).
