Latin Vocabulary by Lesson: Henle First Year Complete Guide

Henle First Year Latin (Robert J. Henle, S.J., Loyola Press) is a common backbone for Logic Stage Latin in classical programs. Its 42 lessons move fast: all five noun declensions arrive in the first six lessons, and the rest of the year layers verbs, the passive voice, the subjunctive, and sentence constructions on top of them. Each lesson adds new words, and the earlier ones keep showing up in the exercises, so the real vocabulary job is keeping the whole list fresh, not just this week’s.

Below is the lesson order grouped into blocks, with notes on where the memory load grows. Lesson topics are summarized in our own words. Check the numbers against your copy of the book, since printings and co-op schedules can differ. For the same material alongside practice links, see our Henle Latin help page.

Lessons 1–6: All Five Declensions

• Lessons 1–5: first through fifth declension nouns, one declension per lesson
• Lesson 6: nouns with special plural forms

Henle front-loads the noun system. Students meet every declension in six lessons, so each new noun has to be learned with its genitive and gender, not just its meaning. The genitive is what tells a student which declension a word belongs to, and that habit carries through the rest of the book. Keep a declension chart nearby until the endings are automatic.

Lessons 7–8: Adjectives

• Lesson 7: first and second declension adjectives
• Lesson 8: third declension adjectives

Adjective-noun agreement is the first big conceptual step. An adjective matches its noun in gender, number, and case, but not always in its ending, which is why vocabulary cards for adjectives should show all three gender forms.

Lessons 9–16: The Active Verb System

• Lesson 9: first conjugation
• Lesson 10: second conjugation in the present, imperfect, and future
• Lesson 11: personal pronouns
• Lessons 12–13: third and fourth conjugation, present active
• Lesson 14: the verb sum
• Lesson 15: the perfect active system
• Lesson 16: more first and second declension nouns

Verb vocabulary gets heavier here. Students need to know which conjugation a verb belongs to, and from Lesson 15 the perfect system makes the principal parts matter: one verb becomes several forms to remember. Teach principal parts as a single unit from the first day a verb appears, rather than adding them later.

Lessons 17–21: The Passive Voice

• Lessons 17–20: the passive system for each conjugation, along with the ablative of agent, means, and accompaniment
• Lesson 21: the perfect passive system

The regular verbs the student already knows now get passive endings (irregular sum has none). Students who are still shaky on the verbs from Lessons 9–15 feel it here, so this is a good point to reopen older lessons in review.

Lessons 22–29: The Subjunctive and Sentence Structure

• Lesson 22: present subjunctive and purpose clauses
• Lesson 23: imperfect subjunctive active
• Lesson 24: relative clauses
• Lesson 25: direct questions
• Lesson 26: perfect subjunctive active system
• Lesson 27: the vocative and the imperative mood
• Lesson 28: suus and sui
• Lesson 29: the passive subjunctive

This block is more about sentence structure than new words, but the relative pronoun and the reflexive forms are small, high-frequency words worth drilling until they are instant.

Lessons 30–34: Participles, Demonstratives, and the Ablative

• Lesson 30: the perfect passive participle
• Lesson 31: hic, haec, hoc
• Lesson 32: the prepositions ex, ab, and de
• Lesson 33: ille and is
• Lesson 34: ablative constructions

Demonstratives are short, common words with irregular forms, so they reward a few minutes of daily review more than a single long session.

Lessons 35–42: Infinitives, Comparison, and Irregular Verbs

• Lesson 35: possum and the infinitive used as a noun
• Lesson 36: numerals and irregular adjectives
• Lesson 37: -io verbs and expressions of time
• Lesson 38: verbs that take the dative
• Lesson 39: the accusative with the infinitive (indirect statement)
• Lesson 40: comparison of adjectives
• Lesson 41: deponent verbs
• Lesson 42: the irregular verb eo

The final block mixes grammar with vocabulary that has to be memorized as exceptions: numerals, irregular adjectives, deponent verbs, and irregular verbs. By this point the translations lean on everything from the first half of the year, so students who kept older words in rotation have the easiest time.

How to Study Henle Vocabulary Effectively

Short daily review works better than cramming a lesson the night before it is due. Study a small number of words each day, and space the reviews further apart as a word gets easier. Each session, start with the current lesson, then mix in a handful of words from older lessons so the cumulative list stays fresh.

A few habits help with Henle in particular:

• Learn every noun with its genitive and gender.
• Learn every adjective with all three gender forms.
• Learn every verb with its principal parts, starting the day it appears.
• Say the words aloud, and go both ways: Latin to English and English to Latin.

Classical Quest’s practice mode includes a Henle lesson picker, so you can narrow review to the lessons your student is studying, and spaced repetition brings words back for review over time. For offline study, the flashcard export tool prints cards for a chapter range, which is useful for car rides, waiting rooms, or screen-free study time. When a sentence will not come apart, our guide to getting unstuck in Henle walks through the grammar and vocabulary habits that help.

You can try the first 50 Latin words with flashcards free, with no signup. Full Henle practice is part of a Classical Quest plan, which carries a 60-day money-back guarantee and starts with a 14-day free trial, with nothing charged during the trial.
