Latin conjugation
Conjugation is the creation of derived forms of a verb from one basic form. It may be affected by person, number, gender, tense, mood, voice or other language-specific factors. When, for example, we use a verb to function as the action done by a subject, most languages require conjugating the verb to reflect that meaning. (For more information on conjugation in general, see the article on grammatical conjugation.)
In Latin, there are five main patterns of conjugation composed of groups of verbs that are conjugated following similar patterns. As in other languages, Latin verbs have a passive voice and an active voice. Furthermore, there exist deponent and semi-deponent Latin verbs (verbs with a passive form but active meaning), as well as defective verbs (verbs with a perfect form but present meaning).
In a dictionary, Latin verbs are always listed with four principal parts which allow the reader to deduce the other conjugated forms of the verbs. These are:
- the first person singular of the present indicative active
- the present infinitive
- the first person singular of the perfect indicative active
- the supine (or, in some texts, the perfect passive participle, which is nearly always identical)
Latin tenses and moods
Latin has the following tenses and moods:
- Active voice
- Indicative: present, imperfect, future, perfect, pluperfect (past perfect), future perfect
- Subjunctive: present, imperfect, perfect, pluperfect
- Infinitive: present, perfect, future
- Imperative: present, future
- Participle: present, future
- Gerund
- Supine
- Passive voice
- Indicative: present, imperfect, future, perfect, pluperfect, future perfect
- Subjunctive: present, imperfect, perfect, pluperfect
- Infinitive: present, perfect, future
- Imperative: present
- Participle: perfect
- Gerundive
Deponent and semi-deponent verbs
Deponent verbs are verbs that are passive in form (that is, conjugated as though in the passive voice) but active in meaning. These verbs have only three principal parts, since the perfect tenses of ordinary passives are formed periphrastically with the perfect participle, which is formed on the same stem as the supine.
Deponent verbs use active conjugations for tenses that do not exist in the passive: the gerund, the supine, the present and future participles and the future infinitive.
Semideponent verbs form their imperfect tenses (present, imperfect, and future) in the manner of ordinary active verbs; but their perfect tenses are built periphrastically like deponents and ordinary passives; thus semideponent verbs have a perfect active participle instead of a perfect passive participle.
Principal parts for the active voice
The first conjugation is characterized by the vowel ā (long a) and can be recognized by the -āre ending of the present infinitive.
- The principal parts of a first-conjugation verb follows the pattern: amō, amāre, amāvī, amātum (to love)
The second conjugation is characterized by the vowel ē (long e) and can be recognized by the -eō ending of the first person present indicative and the -ēre ending of the present infinitive.
- The principal parts of a second-conjugation verb follows the pattern: dēleō, dēlēre, dēlēvī, dēlētum (to destroy), sometimes with a ui in the perfect stem, and itum in the supine, like moneō, monēre, monuī, monitum (to warn).
The third conjugation consists of two sub-forms. The first is characterized by a consonant stem, and the second is characterized by the vowel ǔ (short u). In both cases the present infinitive ends in -ere.
- The third conjugation –iō' is part of the third conjugation. Though its first principle parts always end in an –iō or –ior.
- The principal parts of a normal third-conjugation verb follows the pattern: legō, legere, lēgī, lēctum (to read), the perfect stem characterized by a change of vowel sound (in this case, from 'e' to 'ē'), or the ending si: rego, regere, rexi, rectum (to rule)(g + s = x).
- The principal parts of a special third-conjugation verb follows the pattern: statuō, statǔere, statī, statūtum (to set up)
The fourth conjugation is characterized by the vowel ī (long i) and can be recognized by the -īre ending of the present infinitive.
- The principal parts of a fourth-conjugation verb follows the pattern: audiō, audīre, audīvī, audītum (to hear)
There are also some verbs that are irregular and do not fall into one of the four categories. Some examples include:
- sum, esse, fuī, -- (to be) and its compound forms
- eō, īre, iī (ivī), itum (to go) and its compound forms
- volō, velle, voluī, -- (to want)
- nōlō, nōlle, nōluī, -- (to not want)
- mālō, mālle, māluī, -- (to prefer)
- ferō, ferre, tulī, lātum (to carry or wear)
Some verbs that fall under one of the four categories may follow its method of conjugation but not necessarily have the same progression of principal parts. This is especially true in the third conjugation, where there is no general pattern for the third and fourth principal parts of the verb. For example, the verb occīdō, occīdere, occīdī, occīsum (to kill) is third conjugation but has principal parts that are different from that of legō. These include deponent verbs (which are passive in form, but active in meaning: conor, conari, conatus sum, to try), and semi-deponent verbs, which are active, but have a passive perfect stem (confido, confidere, confisus sum, to trust).
Conjugation radicals
The present infinitive radical is derived by dropping the -āre, -ēre, or -īre from the present infinitive.
The perfect indicative radical is derived by dropping the -ī from the first-person singular perfect indicative:
- amāvī: amāv-
- dēlēvī: dēlēv-
- lēgī: lēg-
The supine radical is derived by dropping the -um from the supine:
- amātum: amat-
First conjugation (ā)
The first conjugation is fairly common. All non-deponent verbs of the conjugation have an infinitive with stem āre. Deponent verbs have ārī. Dare, an irregular verb, does not have a long a in the usual forms. Verbs of this conjugation usually follow the –ō, –āre, –āvī, –ātum pattern. This conjugation is signified by the letter a in the indicative, and an e in the subjunctive.

Second conjugation (ē)
The second conjugation is less prolific. Regular verbs have an –ēre in the second principle part, and deponent verbs have an –ērī. They usually follow the –eō, –ēre, –ui, –itus pattern. The first principle part always ends in an eō or eor. Second conjugation verbs are signified by an ē in the indicative, and an eā in the subjunctive.

Third conjugation (ě)
The third conjugation is fairly common. The verb pradigm shown below is of the regular third conjugation type. However, there is a third conjugation in –iō. For both, there is an –ere for regular verbs in the second principle part, and an –ī for deponent verbs. The third conjugation is by far, the least regular.

Fourth conjugation (ī)
The fourth conjugation is a fairly uncommon. Non-deponents usually end in an –iō in the first principle part. Deponent verbs terminate in an –ior. All fourth present active infinitives end in either –īre or –īrī (deponent). Most verbs of this type have principal parts ending –iō, –īre, –īvī (sometimes replaced with –iī), ītum. This conjugation is signified by an –ī in the indicative, and an –iā in the subjunctive.

Irregular verbs
Syncopated Forms
'Syncopation' (as opposed to 'syncope') occurs when vowels (most often with consonant v or i) are condensed, usually in poetry.
This most commonly occurs with verbs in the perfect tense, when the -vi- (also -ve) is dropped before endings beginning with s and r.
Examples:
- amāvistī becomes amāstī
- amāvistis becomes amāstis
- dēlēvērunt becomes dēlērunt
- dēlēvisse becomes dēlēsse
- audīvissēs becomes audīssēs
This also occurs in nōscō, and compounds of moveō (Charles E. Bennett, New Latin Grammar)
- nōvistī becomes nōstī
- commōverat becomes commōrat
Patterns and Similarities
Notice that in all forms the endings are (at least remotely) similar, 'o' or 'm' endings indicate the first person - I/we . '-s' indicates second person: you ; 't' endings indicate third person - he/she/it/they
So:
- Singular
- -ō/m = I: sum or amo
- -s = You: amas
- -t = He: est or amat
- Plural (note the simularities with the singular)
- -mus
- -tis
- -nt
A few elements of conjugation, often similar to Latin conjugation, survive in English and can serve as helpful mnemonics. 'am' (I am) retains the nasal 'mmm' sound inherited from its ancestors (note: me). is is remarkably similar to the Latin est (cf. German ist). Such similarities are a result of English and Latin's common descent from an Indo-European ancestor.
