This document introduces basic syntactic concepts and categories in clauses. It defines a clause as the key unit of syntax that is capable of occurring independently and describes a complete event or state. Clauses are categorized as independent or dependent, finite or non-finite, and minor clauses are defined as well. The main syntactic elements of a clause are identified as the subject, predicator, direct object, indirect object, and others. Finally, the document discusses verb complementation patterns, identifying intransitive, copular, monotransitive, ditransitive, and complex transitive verbs.
