The speaker discusses various aspects of verbal agreement in Portuguese grammar. Key points include:
1. Compound subjects: When two subjects are connected by "or," the verb can be singular or plural, depending on whether it's exclusive or inclusive.
2. Impersonal verbs: Verbs like "existir" (to exist) and "ter" (to have) are impersonal when used in the sense of existing, and are always in the third person singular.
3. Verb "ser" (to be) with numerals: When describing time or distance, the verb "ser" agrees with the numeral, but when describing a specific date, it can be singular or plural depending on the context.
4. Use of pronouns: When using verbs with pronouns, the verb agrees with the pronoun, not the subject.
5. Prepositions: When using prepositions with verb pronouns, the verb is always in the singular.
