Identifying аntecedents аnd subоrdinаte clauses It is оften impоrtant when attempting to tackle longer sentences to understand how one clause relates to the next. In sentences involving relative clauses, this involves identifying the antecedent which anticipates the relative pronoun. In the following sentence, there are two relative clauses. The relative pronouns are underlined, and the antecedents of each is in bold: Aeacus ōlim regēbat Aegīnam, quae nōmen suum cēperat ā nōmine mātris Aeacī, quācum Iuppiter sē in amōre iūnxerat. We would say that the two relative clauses are subordinate clauses to the main clause, since they depend on the main clause for meaning and context. The main clause is the only clause in the sentence that could be expressed independently and still retain its grammatical integrity: we could have a complete sentence "Aeacus was once ruling Aegina", but the sentences "Which had taken its name from the name of the mother of Aeacus" and "With whom Jupiter had joined himself in love" are not grammatically complete sentence. Because the antecedent of the second relative clause is in the first relative clause, we could say that this is subordinate to a subordinate clause. It can sometimes be useful to diagram these relationships: [main clause:] Aeacus ōlim regēbat Aegīnam [subordinate clause 1:] quae nōmen suum cēperat ā nōmine mātris Aeacī [subordinate clause 2:] quācum Iuppiter sē in amōre iūnxerat. This can be helpful not only when we come to translating, but, more importantly, for seeing clearly the structure of the sentence and how the entirety of a complex sentence relates to the main clause.
