Slovak numbers, while sharing similarities with other Slavic languages, possess unique grammatical and phonetic characteristics that warrant careful examination; this guide systematically addresses cardinal and ordinal numbers, their declension patterns, and practical applications in spoken and written Slovak.
Cardinal Numbers: Foundations
The Slovak cardinal number system follows a decimal structure, with distinct forms for numerals one through ten, which then combine to form larger numbers; the phonetic realisation of these numerals often involves palatalisation or assimilation, particularly in rapid speech.
| Number | Slovak | IPA |
|---|---|---|
| 1 | jeden | /ˈjɛdɛn/ |
| 2 | dva | /dva/ |
| 3 | tri | /trɪ/ |
| 4 | štyri | /ˈʃtɪrɪ/ |
| 5 | päť | /pæc/ |
Higher Numbers and Their Formation
Numbers from 11 to 19 are formed by adding '-násť' to the base numeral, while multiples of ten up to 90 use the suffix '-dsiat', with irregularities appearing in the teens and the number 'twenty' (dvadsať), which derives from an older dual form.
- 11: jedenásť (/ˈjɛdɛnaːsc/)
- 20: dvadsať (/ˈdvad͡zac/)
- 30: tridsať (/ˈtrɪd͡zac/)
- 100: sto (/stɔ/)
Ordinal Numbers and Declension
Ordinal numbers in Slovak, which indicate position in a sequence, exhibit full adjectival declension, agreeing with the noun they modify in gender, number, and case; the formation of these numerals typically involves the addition of suffixes such as '-ý', '-á', or '-é' to the cardinal stem, with suppletive forms appearing in the first three ordinals.
Prvý
/ˈpr̩viː/“First”
Subsequent ordinals follow predictable patterns, though with occasional phonetic adjustments to maintain euphony, particularly in the case of numerals ending in '-dsiaty' (e.g., 'dvadsiaty' for 20th) or '-stý' for hundreds.
Practical Usage and Common Pitfalls
When employing Slovak numerals in context, one must account for the grammatical phenomenon of numeral-noun agreement, where the noun's case is determined by the numeral's value; for instance, nouns following the numerals 2–4 appear in the nominative plural, while those following 5–19 take the genitive plural, a distinction that often challenges learners.
