How to Parse a Latin Verb

To parse a Latin verb is to identify its grammatical features, not merely to translate it. A complete parse of finite mittēbāmus is “first-person plural, imperfect indicative active of mittō, mittere, mīsī, missum.” Only after that analysis should you choose “we were sending,” “we used to send,” or another contextual English rendering.

This form-first habit matters because one Latin form often corresponds to several English phrases, while one English phrase can correspond to several Latin forms. Parsing turns a guess into a sequence of testable decisions.

What a complete parse contains

For a finite verb, report:

1. person: first, second, or third;
2. number: singular or plural;
3. tense: present, imperfect, future, perfect, pluperfect, or future perfect;
4. voice: active or passive in morphology;
5. mood: indicative, subjunctive, or imperative;
6. lexeme, preferably with principal parts;
7. any lexical qualification, such as deponent meaning.

For a non-finite form, person and mood may not apply. An infinitive is parsed for tense and voice; a participle also has case, number, and gender because it declines. See Finite and Non-Finite Forms for those categories.

In mittēbāmus, -mus identifies first-person plural active, -bā- identifies imperfect indicative, and mittē- belongs to the present-stem formation of mittō. The translation is the result, not the evidence.

The five-pass procedure

Pass 1: find the ending

Begin at the right edge. Common present-system active endings are -ō/-m, -s, -t, -mus, -tis, -nt; common passive endings are -r, -ris/-re, -tur, -mur, -minī, -ntur. Perfect indicative active has a distinctive set: -ī, -istī, -it, -imus, -istis, -ērunt.

Claudunt ends in -nt: third-person plural active. The preceding u is a connecting vowel, not part of the person ending.

Clauduntur ends in -ntur: third-person plural passive. Nominative plural portae confirms the agreement; ā mercātōribus is the personal agent.

Pass 2: identify a tense or mood signal

Look immediately left of the ending. Productive markers include imperfect indicative -bā- in the first two conjugations, third/fourth-conjugation imperfect sequences such as -ēbā-, first/second-conjugation future -bi-/-bu-, and characteristic subjunctive vowels. A form shaped like the present infinitive plus endings often signals the imperfect subjunctive.

Manērēmus ends in -mus, so it is first-person plural active. The base manēre- before the ending points to imperfect subjunctive. The ut clause after a past request confirms that analysis.

Pass 3: choose the stem family

Relate the remaining material to the principal parts. The present stem builds the present system; the third principal part supplies the perfect active stem; the fourth principal part or perfect passive participle supplies the supine family.

Relīquērunt has third-person plural perfect active -ērunt. Its stem relīqu- comes from the third principal part relīquī, not directly from present relinquō or from English “left.”

Relictus erat is third-person singular pluperfect indicative passive of relinquō, relinquere, relīquī, relictum. The supine-family participle relictus agrees with masculine singular pons; imperfect erat makes the compound form pluperfect.

Pass 4: use syntax to resolve ambiguity

Morphology may leave more than one possibility. Amāverit can be future perfect indicative or perfect subjunctive, both third-person singular active. Clause structure and time reference must decide. Likewise dūcere can be the present active infinitive, an alternative second-person singular present indicative passive, or the second-person singular present passive imperative; syntax distinguishes the three analyses.

In this future context, scrīpserit is naturally future perfect indicative: the writing will be complete before discēdet. In a clause of result or indirect question, the same ending sequence could be perfect subjunctive.

Here dūcere is the alternative second-person singular present indicative passive, equivalent to dūceris. Nominative tū marks it as a finite second-person predicate rather than an active infinitive, whose expressed subject would be accusative; the direct cūr question rules out a command. This -re ending is normal Classical Latin, though learners more often meet -ris first.

Pass 5: check lexical behavior

Consult the lexeme’s entry. Passive-looking loquitur is present indicative third-person singular deponent: passive in form, active in meaning. A form of defective meminī belongs morphologically to the perfect system but has present meaning.

Outwardly, locūtus est resembles a perfect passive. The principal parts loquor, loquī, locūtus sum identify a deponent, so the correct complete parse adds “deponent, active in meaning.”

Do not let translation erase aspect

Latin tense labels are grammatical categories, not fixed English phrases. Present scrībit may mean “writes” or “is writing.” Perfect scrīpsit may mean “wrote” or “has written.” Imperfect scrībēbat may mean “was writing,” “used to write,” or, in a suitable narrative, “kept writing.”

Imperfect legēbam supplies the ongoing background; perfect scrīpsit presents a complete event. Translating both merely as “past” would miss the contrast that the author selected.

A compact worked analysis

Take moneāmur in Magister vult ut moneāmur “the teacher wants us to be warned.”

1. -mur gives first-person plural passive.
2. The characteristic present-subjunctive vowel is -ā- after the second-conjugation base mone-.
3. The base belongs to moneō, monēre; its dictionary long ē is shortened before the following vowel in moneāmur.
4. The ut clause after vult supports subjunctive.
5. Complete parse: first-person plural, present subjunctive passive of moneō, monēre, monuī, monitum.

The visible long and short vowels matter. In teaching forms, macrons distinguish shapes that unmarked ancient and many modern editions leave ambiguous. When reading an authentic unmacronized text, syntax and lexical knowledge do more of the work.

Common Mistakes

1. Giving only an English translation

2. Reading the final letters without finding the tense marker

3. Building a form backward from English

4. Ignoring deponent status

Key Takeaways

Parse from form to function: ending, tense or mood signal, stem family, syntactic context, then lexical behavior. Report every applicable category before translating. Principal parts resolve stem changes, syntax resolves genuine ambiguity, and dictionary knowledge identifies deponent or defective behavior. English is the destination of the analysis, never its starting point.
