Slovak, like most Slavic languages and Latin, is an inflected language, meaning that the endings (and sometimes also the stems) of most words (nouns, adjectives, pronouns and numerals) change depending on the given combination of the grammatical gender, the grammatical number and the grammatical case of the particular word in the particular sentence:
a) Gender: There are four grammatical genders in Slovak: animate masculine, inanimate masculine, feminine, and neuter. In popular description, the first two genders are often covered under common masculine gender. Almost all Slovak nouns and adjectives, as well as some pronouns and numerals can be categorized into one of these genders. Exceptions are pluralia tantum (Vianoce – Christmas, though there are rules for deriving the gender), words that are drifting into another gender and are currently neuter (knieža – prince), and masculine animals that are animate in singular and mostly inanimate in plural.
b) Number: Like in English, Slovak has singular and plural nouns. Morphological traces of the ancient Indo-European dual number remain, but are not a separate grammar category anymore.
A particular case is associated with three distinct groups of numerals associated with nouns:
c) Morphological cases:
- the nominative case (N) = the subject; the basic form of the word; answers the question Who / What; for example father (sg), fathers (pl)
- the genitive case (G) =
- (1) in English "of x" or "x's"; answers the questions Of whom / Of what; for example father's (sg. ), fathers' (pl);
- (2) is used after the prepositions bez (without), blízko (near), do (to, into), doprostred (in(to) the middle of), mimo (out(side) of), miesto (instead of), okolo (around), od (from), podľa (according to), pomimo (next to, around), pomocou (by means of), pozdĺž (along), u (at), uprostred (in the middle of), vedľa (next to, adjacent to), vnútri (in, inside of), vyše (above), z (out of, from), *za (behind)
- the dative case (D) =
- (1) in English "to x"; answers the question To whom / To what; for example to the father (sg), to the fathers (pl);
- (2) is used after the prepositions k (to, towards), kvôli (because of), napriek (in spite of), naproti (facing, opposing), oproti ((facing, opposing)), voči (facing, against)
- the accusative case (A) =
- (1) the direct object; answers the question Whom / What; for example [I see the] father (sg), fathers (pl);
- (2) is used after the prepositions: cez(through), *medzi (between, among), *na (on, at), *nad (above), *po (after, for), *o (about, on), *pod (under), pre (for, because of), *pred (before, in front of), *v (in, on), vzhľadom na (regarding, concerning), *za (behind, for)
- the locative case (L) = used after the prepositions *na (on), *po (after), *o (about, on), pri (at, next to), *v (in, on)
- the instrumental case (I) =
- (1) in English "by (means of) x"; answers the question By (means of) whom / By (means of) what; for example [written] by the father;
- (2) is used after the prepositions: *medzi (between, among), *nad (above), *pod (under), *pred (before, in front of), s (with), *za (behind, at the back of)
- The (syntactic) vocative case (V) is not morphologically marked anymore in modern Slovak (unlike in modern Czech). Today the (syntactic) vocative is realised by the (morphological) nominative case, just like in English, German and many other languages. However, the ancient vocative declensions have survived (mostly in conserved, archaic words or language, e.g. in fairy tales, folklore, or in an ironic sense) in some words, some examples: syn (son) – V: synku, brat (brother) – V: bratu, bratku), chlapec (boy, knave) – V: chlapče), švagor (brother-in-law) – V: švagre or N, kmotor (godparent) – V: kmotre or N), chlap (man, male) – V: chlape, priateľ (friend) V: priateľu or N, pán (mister, lord) – V: pane or N), majster (master artist) – V: majstre or N), boh (god) – V: bože, mama (mum, mother) – V: mamo, mami) and was retrofitted (with the help of Czech influence) to some more words, like šéf (chief, boss) – V: šéfe. There is a dispute among some Slovak linguists whether to include the vocative into the categories grammar, but with declension (mostly) equal to the nominative, or to unify it with the nominative case category. The morphological vocative is used only for the above restricted number of words and in addition only in some contexts (such as many dialects, which still use the vocative case). Note however that there is no dispute that the syntactic vocative exists in Slovak. Slovak schools have been teaching for at least 30 years that there is no grammar category of vocative anymore in use, however, the use of the vocative case in the past is often mentioned. The Slovak Encyclopedia of Linguistics (1993) explicitly says: the vocative is nowadays replaced by the nominative. However, the Slovak National Corpus explicitly includes vocative as a separate case in the morphological analysis and corpus tagset.
There is also a different form of morphological vocative emerging in spoken language, used with some familiar forms of personal names (Paľo - Pali, Jano, Jana - Jani, Zuza - Zuzi) and familiar forms of kinship words, such as mama – mami (mum, mother), oco – oci (dad, father), tata, tato – tati (dad, daddy), baba, babka – babi (gran, granny, grandmother). This usage is very similar to the "new Russian vocative" (Маш', Петь', мам'), but it is not accepted into standardised codified language.[citation needed] This could have developed out of proper names that were formed using the Hungarian diminutive suffix -i and that are used in spoken Slovak, and therefore is often homonymous with nominative (semi-)diminutive forms of the names. Another possibility is influence from Czech (from common bilingual TV during Czechoslovakia), where Jani / Zuzi as well as mami / tati / babi is part of Common Czech.
