Learn the fourth principal part, which governs the formation of the perfect and pluperfect tenses. Discover the great utility of these past tenses for talking about completed action. Study an example of the perfect in John 3:13, and read lines 17-21 of the Iliad.

Bring your study of Greek verbs to a close by focusing on an important class of verbs that end in μι in the first principal part. There aren’t many such μι verbs, but they are useful and common, and they appear frequently in compounds.

Conclude your exploration of Greek pronouns with interrogative, indefinite, and relative pronouns. These are words such as who, which, and what; and, for indefinite pronouns, someone, something, and similar unspecific descriptors. Look at examples in the New Testament and in the Iliad 81-85.

Delve deeper into the aorist passive, which was introduced in Lesson 19. This tense may sound exotic, but it’s a workhorse in Greek sentences. For example, study the string of aorist passive commands in the Lord’s Prayer in Matthew. Then work your way through lines 59-63 of the Iliad.

Unravel the long history of how nonverbal communication has evolved, how and why we originally interacted with others, and how the biological history of our bodies suggests that our ability to communicate verbally was so limited, the only way we could send messages to friends and foes was through facial expressions and body language. You’ll also explore the seven emotions communicated most strongly and accurately through our faces.

Although first declension nouns are generally feminine, some masculine nouns also fall into this class. Learn how to recognize them (as well as the declensions of all nouns) from the nominative and genitive forms supplied in Greek dictionaries. Then investigate some finer points of compound verbs.

How good are we at reading people? Can we train ourselves to be better at this skill, or is it an inherent ability? This lecture explores a number of studies that measure the ability to read facial expressions, voice and tone, and body language. Get some tips for improving your own ability to read nonverbal communication.

Look at two variations in the pattern of the first declension—one used in Homeric Greek and the other in Koine, the Greek of the New Testament. Despite being separated by almost a thousand years, the two dialects have remarkable continuity.

Confront the often-confusing question of when to use that" as opposed to "which." Study the most commonly applied rules governing these relative pronouns, and hear opinions on the subject from notable grammarians. Also learn about clauses in which relative pronouns disappear, and consider the use of relative pronouns with animate beings vs. inanimate objects.

Determiners are small words (such as an," "this," "each," or "many") that introduce nouns and create noun phrases. Learn their key functions in English, and see how determiners are different from adjectives and pronouns. Then investigate the history of capitalization in English, current capitalization practice, and the curious history of the capitalized pronoun "I."
