Case, Number, Gender, Person, Tense, Voice, and Mood

To parse a Latin form is to identify the grammatical features it expresses. Nouns, adjectives, and pronouns chiefly mark case, number, and gender; finite verbs mark person, number, tense, voice, and mood. These features interact across a sentence: adjectives agree with nouns, verbs agree with subjects, and cases show how noun phrases participate in an event.

English expresses some of the same distinctions, but often through word order and separate words. Latin places much more of the evidence in endings. The practical rule is therefore: identify the form before translating the sentence. All unlabelled forms below belong to neutral Classical prose.

The feature map

No ending should be interpreted in isolation. For example, noun ending -īs may be dative or ablative plural, and -a has many possible analyses across declensions. A parse is first a list of formally possible features and then a contextual decision.

Case: relation, not position

Case marks the role or relation of a noun phrase. The nominative commonly marks a subject, the accusative a direct object, the genitive a dependent such as a possessor, the dative a recipient or interested party, and the ablative a broad range including means, separation, and circumstance. These are core tendencies, not one-to-one translations: no single English preposition captures “the ablative,” and many case uses take no preposition at all. The six core cases and the locative are treated individually later in the guide.

Lūcia is nominative singular, epistulam accusative singular, and sorōrī dative singular. English depends heavily on order and to; Latin uses three different endings.

The participants have not changed. The marked order shifts attention toward sorōrī, but the cases still identify subject, object, and recipient. Latin order is meaningful, not mechanically fixed.

Number and gender: the agreement network

Latin has singular and plural. Number appears on nouns and on the words that agree with them. It also appears on finite verbs, which normally match their subjects. Some nouns occur predominantly in only one number, and agreement by sense occasionally competes with strictly formal number (literary), but ordinary beginners should first master regular number agreement.

Singular mercātor goes with adest; plural mercātōrēs goes with exspectant. The endings, not an English article, carry the contrast.

Gender is a lexical classification of nouns: masculine, feminine, or neuter. It often corresponds to sex with words for people, but it is not the same thing as biological sex. Agricola “farmer” is masculine despite its first-declension -a; mālum “apple” is neuter. Adjectives and certain pronouns take the gender, number, and case required by the noun they modify.

Masculine nominative singular fessus agrees with masculine agricola. Declension and gender are related classifications, but they are not identical.

Neuter mālum requires neuter hoc and corruptum. English adjectives do not change for agreement, so English speakers must deliberately build this network when reading Latin.

Person: the subject inside the verb

First person includes the speaker (I, we), second person addresses the listener (you), and third person refers to someone or something else (he, she, it, they). A finite Latin verb normally identifies person and number in its ending. Subject pronouns are consequently omitted unless contrast, emphasis, or clarity calls for them.

The pronouns ego and tū make the contrast explicit. Without contrast, scrībō and recitās already contain enough information to recover the subjects.

Tense: time viewed through a form

Latin tense combines location in time with aspectual viewpoint. The imperfect normally presents a past situation as ongoing, repeated, or backgrounded; the perfect presents it as a complete event or a resulting state. Translation is therefore not a mechanical replacement of one Latin tense by one English tense.

Scrībēbam uses the present stem scrīb-, imperfect marker -ēbā-, and first-singular ending -m. It provides the ongoing background. Perfect vēnit presents the arrival as a complete event.

Both perfects move the completed sequence forward. English happens to use its simple past here, but in another context Latin perfect may correspond to English “have written.” Learn the Latin contrast, not a fixed English label.

Voice: what kind of subject?

In the active voice, the grammatical subject is typically the actor: servus iānuam claudit, “the slave closes the door.” In the passive, the subject is the participant affected: iānua ā servō clauditur, “the door is closed by the slave.” Present-system passive voice is often marked directly in the ending; perfect-system passive forms combine a participle with sum.

Clauditur ends in -tur, third-person singular passive. The nominative iānua controls its number; ā servō names the personal agent.

Deponent verbs are the major lexical exception: they use passive-looking forms with active or non-passive meanings. This is not optional stylistic voice choice.

Proficīscimur has first-person plural passive morphology but is the normal active-meaning form of deponent proficīscor. The dictionary label dep. is essential evidence.

Mood: how the clause is presented

Mood is not emotional “mood.” It marks how a verbal event is presented and how a clause is grammatically organized. The indicative normally makes assertions and asks direct factual questions. The subjunctive serves independent wishes, commands, possibilities, and many subordinate constructions. The imperative issues direct commands.

The lexical idea is stable, but indicative venit, subjunctive veniat, and imperative venī present it differently. In subordinate clauses, an English translation may not contain a special word corresponding to the Latin subjunctive; the mood can be required by Latin syntax itself.

A reliable feature-reading order

For a noun or adjective, state part of speech → case → number → gender → dictionary form → function. For a finite verb, state person → number → tense → voice → mood → dictionary form. Thus amābuntur parses as third-person plural future passive indicative of amō: amā- + future marker -b- + linking vowel -u- + passive ending -ntur.

The nominative plural fīliī agrees with plural laudābuntur. The form itself rules out “he will praise,” no matter where the words stand.

Common Mistakes

1. Guessing subject and object from English order

2. Treating declension as gender

The first-declension ending does not make poēta feminine.

3. Ignoring person in the verb ending

4. Reading a deponent as an ordinary passive

5. Treating the subjunctive as a future tense

Key Takeaways

Nominal features form an agreement network of case, number, and gender; verbal features package person, number, tense, voice, and mood. Endings narrow the possibilities, but syncretism and lexical exceptions mean that morphology and syntax must cooperate. Parse the Latin evidence first and choose the most natural English expression only afterward.
