Estonian grammar

Inflectional endings as listed below are added to the stem of a noun, which is formed from:

• singular genitive: singular cases except nominative and partitive, plural nominative,
• singular partitive: plural genitive,
• plural genitive: plural cases except nominative and partitive.

Singular nominative, singular genitive and singular partitive are not predictable and have to be taken from the vocabulary (gradation may also apply).

Singular genitive always ends in vowel. When formed from a stem that ends in consonant, it can take the following endings: -a, -e, -i, -o, -u.

Singular partitive can take the following endings: -d, -t, -a, -e, -i, -u.

Plural partitive is formed from either singular genitive or singular partitive and can take the following endings (some words have two forms):

• -id: one-syllable words with long vowels aa, ee, õõ, uu, öö, ää, two-syllable words with long vowels or endings -em, -en, -el, -er, -ar, -ur, -e, -ne, -s or singular genitive with one or three syllables, three-syllable words with endings -ne, -s,
• -sid: one-syllable words with long vowels ii, üü or a diphthong, two-syllable words with short vowels, three-syllable words with endings -um, -on, -er, -ar, -är, -ov, -nna,
• -e: words with singular partitive endings -i, -u, -j, or singular partitive ending -a with the preceding syllable containing u,
• -i: words with singular partitive ending -e, or singular partitive ending on consonant with singular genitive ending -e, or singular partitive ending -a with the preceding syllable containing vowels e, o, ä, ö, ü or a diphthong with one of these vowels as the first sound with the exception of ei, äi,
• -u: words with singular partitive ending -a with the preceding syllable containing vowels a, i, õ or diphthongs ei, äi.

Singular illative has a short form in some words. It can take the following endings: -de, -he, -hu, -a, -e, -i, -u. In case it takes the vowel ending, this vowel is the same as the ending vowel of the singular genitive form of the given word, but the vowel (if it is already long or a diphthong) or its preceding consonant (if the vowel is short and the consonant either short or long) is lengthened to the third degree and thus becomes overlong. If illative ends with -sesse, then the short form is -sse.

Plural illative, inessive, elative, allative, adessive, ablative, translative have a short form in some words. If the plural partitive ends with -id, then the short plural stem is this form without -d (instead of plural genitive with -de-); if it ends with a vowel, then the short plural stem is this form; if it ends with -sid, then the short plural cannot be formed.

Emphasis: noun + -gi (after a final voiced consonant or vowel) / -ki (after a final voiceless consonant).

New nouns can be derived from existing nouns, adjectives and verbs using suffixes like -ja (agent, from -ma infinitive), -mine (gerund, from -ma infinitive), -la, -nna, -tar, -ur, -stik, -ndik, -nik, -ik, -k, -ng, -lane, -line, -kene, -ke, -e, -ndus, -dus, -us, -is, -kond, -nd, -istu, -u.

There are traditionally considered to be 14 noun cases in Estonian:[1]

Locative cases make up six or eight of these fourteen (depending on interpretation).

There are also some additional cases such as the prolative (jalgsi, "by foot"; käsitsi, "by hand"),[2] or the similarly formed instructive (meritsi, "by the way of the sea"), which are not traditionally counted among the 14 grammatical cases.

Inflectional endings as listed below are added to the stem of an adjective, which is formed like the one for nouns.

The stem for the comparative and superlative forms is the singular genitive of an adjective; if a word has two syllables in the genitive or a vowel following -ke(se), then -ke(se) is left out and the last vowel in the stem changes to -e. The genitive and the partitive of the comparative itself are formed with -a and -at.

New adjectives can be derived from existing words by means of suffixes like:

-v (active present participle, from -ma infinitive),

-nud (active perfect participle, from -da infinitive),

-tav (passive present participle, from -tud participle),

-tud (passive perfect participle), and -lik, -line, -lane, -ne, -ke, -kas, -jas, -tu.

Antonym can be formed by prepending eba or mitte to an adjective. Eba- is considered to be the only derivational prefix in Estonian; as mitte can also occur as a separate word, mitte + adjective can be regarded as a compound rather than derivative. Alternatively, for an adjective formed from a noun or a verb, an antonym can often be constructed using the suffix -tu or -matu.

The following lists are not exhaustive.

The inflectional endings as listed below are added to the stem of a verb, which is formed from:

• indicative mood active voice singular first person of positive present tense (by dropping -n): indicative mood active voice of present tense, conditional mood active voice of present tense, imperative mood active voice singular second person of present tense,
• -ma infinitive (by dropping -ma; if the stem ends with a consonant, an additional -i- is added in the singular third person of the imperfect or an additional -e- is added in the singular nominative of the participle, the consonant is doubled if it was short and preceding a short vowel; if the stem ends with -e while being two-syllable or if it ends with a long vowel, then the -s- is left out in all numbers and persons, ei is changed to i, a long vowel becomes short and o, ö are changed to õ): indicative mood active voice of positive imperfect, quotative mode active voice of present tense,
• -da infinitive (by dropping -da / -ta / -a; long final l, r become short, in spoken language -nud is shortened to -nd): indicative mood active voice of negative imperfect, indicative mood active voice of pluperfect, imperative mood active voice of present tense except singular second person, active voice of perfect,
• participle of passive voice perfect (by dropping -tud): passive voice.

Present tense form and -tud participle are derived from the infinitives on the basis of gradation.

-ma infinitive indicates action that has either happened, is happening or will happen. It can be declined: -ma (illative), -mas (inessive), -mast (elative), -maks (translative), -mata (abessive).

-da infinitive indicates hypothetical action, i.e. the action in general. It is used, for example, following ei, et (in order to), and oskama/võima (can). It can be declined: -des (inessive).

Verb derivation: -ta- (transitive/passive), -u- / -i- (reflexive), -el- / -le- (reciprocal), -ne- (translative), -ata- (momentane), -el- / -skle- (frequentative), -tse- (continuous).

• singular genitive of an adjective (-sti, -ti, -ldi, -li, -kesi): genetival type,
• singular ablative of an adjective (-lt; some are declinable in allative, adessive, ablative): ablatival type.

Some adverbs are special words - original or vestigial forms of an ancient instructive case.

The neutral word order in Estonian is subject–verb–object (SVO). Conjunctions: aga (but), et (that), ja (and), kas (whether), kui (if), nagu (as), sest (because), või (or). Questions begin with an interrogative word (interrogative pro-forms or kas (yes/no-question), eks (yes-question), ega (no-question)), followed by the SVO word order (in spoken language, interrogative words are sometimes left out, but instead there is either a change in intonation or VSO word order); answers: jah/jaa (yes), ei (no). An adjective precedes the noun it modifies. An adverb of time precedes an adverb of place.

However, as one would expect from an agglutinative language, the word order is quite free and non-neutral word order can be used to stress some parts of the sentence or in poetic text, as in Finnish grammar. For example, consider the sentence mees tappis karu which means (a/the) man killed (a/the) bear and uses the neutral SVO word order. The sentence can be rephrased using OVS word order as karu tappis mees — a normal Estonian sentence that could be more precisely translated as it was (a/the) man who killed the bear, i. e. the sayer emphasizes that the killer was a man, probably assuming the listener knows that a bear was killed. The other four word orders (tappis mees karu, tappis karu mees, mees karu tappis, karu mees tappis) are also possible in certain contexts, especially if more words are added to the three-word sentences.

Sometimes the form of the verb, nouns and adjectives in the sentence are not enough to determine the subject and object, e. g. mehed tapsid karud (the men killed the bears) or isa tappis karu (father killed the bear) — in the first sentence because in plural, the nominative case is used in Estonian both for subject and telic object, and in the second sentence because in singular, the nominative, genitive and partitive forms of the word isa are the same, as well as those of the word karu (unlike the word mees which has different forms: sg. nom. mees, sg. gen. mehe, sg. part. meest). In such sentences, word order is the only thing that distinguishes the subject and the object: listener presumes that the former noun (mehed, isa) is the subject and the latter (karud, karu) is the object. In such situations, the sayer cannot interchange the subject and the object for emphasis (at least unless it is obvious from the context which noun is the subject).
