Introduction

Etymology

From Latin celsus.

Features

Phonological

• Preserves original vowel length and quality.
• Preserved long nasal vowels into its recent history, then merged them with plain long vowels (but they are kept distinct in writing).
• Original velars became alveolar/dental fricatives/affricates before /i/ and postalveolar fricatives/affricates before /e/.
  • This is because palatalization before /i/ and before /e/ occurred separately at different times.
• Original labiovelars became plain velars in all positions.
• Innovated hard/soft consonant distinction.
• Glide v- inserted before word-initial o- (long or short).
• Glide j- inserted before word-initial e- and i- (long or short).
• Original au preserved as a diphthong.
• Original ae merged with long e in most cases, but was kept distinct in 1st declension noun inflectional endings (later merged in pronunciation but without palatalization).
  • This may have actually been through an intermediate phase -āī rather than descending directly from Classical Latin -ae.
• Original oe merged with long e in all cases.

Grammatical

• Preserves case inflection.
• No articles.
• Modifier precedes noun.

Consonants are always palatalized (soft) before ⟨e, ē, ę, i, ī, į⟩. Before ⟨a, ā, ą, æ, o, ō, ǫ, u, ū, ų⟩, palatalization is denoted by inserting an ⟨i⟩ between the consonant and the vowel.

Uniquely, ⟨j⟩ is always palatalized regardless of position.

Prosody

Stress

Stress generally follows Classical Latin rules. However, contracted forms retain stress on the same syllable that is stressed in the corresponding uncontracted form, or on the syllable it is absorbed into.

Pronouns

Personal pronouns

Notes:

¹ The cases have been reordered for convenience, since nominative & accusative forms are often identical as are dative & ablative. The vocative has been excluded since it is always identical to the nominative except in the 3SM, where it is isse.

² In addition to undeclined genitives, personal pronouns have declined possessive forms.

Verbs

Verbs are split into four conjugations that can be identified by their present active infinitive endings:

• 1st conjugation: -(i)āre
• 2nd conjugation: -ēre
• 3rd conjugation: -ere
• 4th conjugation: -īre

Principal parts

The full conjugation of all verbs (except the verb jessere "to be") can be derived from their principal parts.

The principle parts are:

• 1st person singular present indicative - from which the secondary present stem is derived
• Present active infinitive - from which the primary present stem is derived
• 1st person singular perfect indicative - from which the perfect stem is derived
• Supine - from which the supine stem is derived

Forms based on the present stem

The present stem is obtained by removing the infinitive ending (-(i)āre, -ēre, -ere, or -īre) from the second principal part and (in the case of the first conjugation) maintaining its hardness/softness.

Many verbs in the second to fourth conjugations (and a few verbs in the first conjugation) have a secondary present stem distinct from the primary present stem. This is obtained by removing -(i)ō from the first principal part and maintaining its hardness/softness.

Non-finite forms based on the present stem

Notes:

¹ Uses the secondary present stem (if applicable). First conjugation verbs with an irregular secondary present stem use alternative present subjunctive endings identical to those of the remaining conjugations.

As indicated in the above tables, the secondary present stem is used in the following cases:

• All conjugations:
  1. 1S present indicative
  2. Present subjunctive
• Additional for 3rd and 4th conjugations:
  1. 3P present indicative
• Additional for 4th conjugation only:
  1. Imperfect tense
  2. Present active participle
  3. Present passive participle
  4. Obligative active participle

Otherwise, the primary present stem is used.

Forms based on the perfect stem

The perfect stem is obtained by removing -ī from the third principle part.

Non-finite forms based on the perfect stem

Perfect stems ending in monophthong + -v- can optionally be contracted in certain environments. Note that the stress is always maintained as in the uncontracted form.

Optional contractions of perfect-stem forms

Monophthong preceding -v-	Sequence following -v-	Contraction	Remarks
ā	ī; stressed i, ē	ai	Can become ā before a consonant cluster.
	e; unstressed i, ē	ā or au		o, ō, u, ū	au

u, ū	ī; stressed i, ē	ui	Can become ū before a consonant cluster.
	e; unstressed i, ē	ū
	o, u, ū	ū
	ō	ō

These contractions also occur optionally in other environments.

In regular verbs, the perfect stem can be derived from the present stem in predictable ways:

• 1st conjugation: -āv-
• 2nd conjugation: -uv- (with hard stem-final consonant)
• 3rd conjugation: -uv- (with hard stem-final consonant)
• 4th conjugation: -īv-

The majority of 1st and 4th conjugation verbs are regular, while 2nd and 3rd conjugation verbs (particularly 3rd conjugation) have a higher tendency to have irregular perfect stems.

Irregular perfect stems formations include:

• -ēv-, -ōv- (for some 2nd and 3rd conjugation verbs).
• Adding -s- after the stem-final consonant (which may cause assimilation).
• Replacing -šč- with -v- and lengthening the preceding vowel if short (for 3rd declension verbs with infinitives ending in -ščere and 1S present indicative in -skō).
• Reduplication.
• Vowel lengthening with or without vowel change.
• Dropping nasal infix from present stem.
• No change from present stem.

Forms based on the supine stem

The supine stem is derived from the fourth principle part by removing the ending -ų.

Non-finite forms based on the supine stem

Form	Formation
Supine	-ų (acc.), -ū (dat./abl.)
Perfect active participle	-ęs, -entis, -entių
Perfect passive participle	-us, -a, -ų
Obligative passive participle	-ūrus, -a, -ų

For regular verbs, the supine stem is formed from the present stem as follows:

• 1st conjugation: -āt-
• 2nd conjugation: -ūt-
• 3rd conjugation: -ūt-
• 4th conjugation: -īt-

Verbs with an irregular perfect stem generally also have an irregular supine stem.

• If the perfect stem ends in a monophthong followed by -v-, the supine stem generally ends in the monophthong (lengthened if short) + -t-.
• Otherwise, the supine stem cannot be predictably derived based on the perfect stem. Possible endings (besides the already mentioned ones) include:
  • -t- (possibly with assimilation)
  • -s- (possibly with assimilation)
  • -it-

Note that some verbs with a regular perfect stem may have an irregular supine stem and vice versa.

Compound tenses

Compound tenses are formed with auxiliary verbs.

Compound tenses

Tense	Formation	Remarks
Future	present tense of īre "to go" + supine (acc.)	This can be made into a future-in-past form by instead using the appropriate past tense form of īre.
Future perfect	present tense of īre "to go" + perfect active infinitive
Compound perfect	appropriately conjugated form of avēre "to have" + past participle (acc. neuter, or same gender as direct object)	A compound perfect can be formed from any tense.

Compound non-finite forms

Form	Formation
Future active infinitive	īre + supine (acc.)
Future perfect active infinitive	īre + perfect active infinitive
Future active participle	jęs, -entis + supine (acc.)

Obligative

An obligative counterpart can be made from any tense. It is formed from its declarative counterpart by replacing the main verb with the appropriately conjugated form of jessere "to be" followed by the active or passive obligative participle.

The verb jessere "to be"

The verb sų, jessere, fuvī, fūtų "to be" is one of the most important verbs, and one of the most irregular. In fact, it is the only verb whose full conjugation cannot be determined based on its principle parts.

The forms based on the perfect and supine stems are formed regularly. However, the forms based on the present stem are formed irregularly.

Non-finite forms based on the present stem

Notes:

¹ These are actually the imperative forms of fīre "to become" (principal parts: fiō, fīre, fīvī, fītų); jessere does not have its own imperative.

Other important irregular verbs

Irregular forms are underlined.

Note that class 3 has the most irregular verbs.

veniō, venīre, vēnī, ventų	to come

Lexical aspect

While aspect is primarily expressed through verb conjugation (like Romance languages and unlike Balto-Slavic languages), there is a tendency towards certain verbs having inherent aspect. These verbs generally also have causative counterparts.

"Imperfective" and "perfective" can alternatively be referred to as "stative" and "inchoative" respectively.

Some examples of imperfective-perfective-causative counterparts are given below. Note that the counterparts are not necessarily fully synonymous besides aspect, and they may have alternative meanings that are not shared.

dormiō, dormīre, dormīvī, dormītų	to be asleep	dormīskō, dormīščere, dormīvī, dormītų	to fall asleep	—	—	Many verbs have inchoatives formed with the suffix -skō, -ščere. Such inchoative verbs often share their third and fourth principal parts with the verb they are derived from.

Note that in perfect/supine tenses and the imperative, imperfective verbs can become almost synonymous with their perfective counterparts, and in some cases they are homophonous - e.g. stetī ≈ sūršī "I stood". However, in certain contexts, their meanings are distinct - e.g. Sūršī jet stetī duvās ōrās. "I stood up and remained standing for two hours."

In imperfect tenses (i.e. the present indicative and the imperfect indicative and subjunctive), perfective verbs tend to become inchoative in meaning - e.g. suržēvą "I was standing up/stopping, I used to stand up/stop" vs. stāvą "I was standing, I used to stand".

If needed, for verbs without lexical aspect, imperfective can be explicitly marked using jessere + present participle, while perfective can be marked with fīre + present participle (if not already marked via compound perfect or other means).

Facere + infinitive is used to form analytical causatives.
