A feminine rhyme is when there is an extra unstressed syllable at the end of the line. "I come to bury Caesar, not to praise him." In this case "him" is the extra syllable.
A trochaic meter is when two syllable words. The stress pattern is / - like the word season. This is used to command attention like Antony's start of his speech.
Rhetoric is the art of persuasion in speech or writing. In Julius Caesar a common theme is persuasion, thus there is plenty of rhetoric throughout the play.
An oration is a more sophisticated word for speech. Julius Caesar is famous for quite a few orations. The most popular is probably Mark Antony's funeral speech, "Friends, Romans, Countrymen".
In the funeral speeches of both Mark Antony and Brutus they ask rhetorical questions. These are a very persuasive technique that help them get the audience on their side by asking questions when they do not want the questions to be answered.
Dramatic irony is when the audience knows something that characters do not know. For example, Mark Antony states he plans to seek revenge in his funeral speech. The audience knows this, but Brutus does not.
Situations irony is when someone tries to do one thing and the opposite happens. For example Brutus tries to free Rome from tyranny, and he ends up leaving Rome in the hands of a tyrannical leader.
Verbal irony is when someone says one thing, but means another thing. Mark Antony's use of the word "honourable" is an example of verbal irony.
