A concept map about the subject designed to explain clearly what the subject is and how to identify it in a sentence. The map shows that the subject is the element being talked about and explains how it agrees with the verb in person, number and, sometimes, gender. It also presents the different parts of speech that can function as the subject, including a noun, pronoun, infinitive verb, adjective and adverb, and distinguishes between explicit and implicit subjects. A useful Italian grammar summary for studying, reviewing and improving understanding of sentence structure.
