Czech adjectives are primarily divided into two groups for declension: hard and soft. This classification is based on the stem-ending of the adjective.
Hard Adjectives (Tvrdá adjektiva)
- Nominative Masculine Singular Ending: Usually ends in -ý.
- Examples:
- nový (new)
- mladý (young)
- dobrý (good)
- The endings are characterized by hard vowels, particularly -ý, -á, -é. For instance, the masculine nominative singular is -ý, while the feminine is -á and the neuter -é.
Soft Adjectives (Měkká adjektiva)
- The stem ends in a soft consonant such as c, j, ž, š, č, ř, but also endings such as -ní or -cí.
- Nominative Masculine Singular Ending: Always ends in -í.
- Examples:
- cizí (foreign)
- jarní (spring, of spring)
- rybí (fish, of fish)
- Declension Pattern: The endings are consistently characterized by the soft vowel -í across all genders and numbers. For example, the nominative singular for all genders (masculine, feminine, and neuter) is -í. There are no changes like -ý to -á. The only change occurs in the plural dative case, where it becomes -ím, and in the locative/instrumental cases, which can have different endings depending on gender and number.
Thus, the basic form of an adjective describes a quality without any comparison. For example:
- pomalý (slow)
- krásný (beautiful)
- starý (old)
Comparative Form
The comparative form is used to compare two things. In Czech, this is typically formed by adding the suffix –ejší, -ější or -ší to the adjective. For example:
- pomalejší (slower) from pomalý
- krásnější (more beautiful) from krásný
- starší (older) from starý
It expresses a higher degree of quality compared to another object/person.
It is formed using the suffixes:
-jějí: for adjectives ending in a consonant (eg: more beautiful, stronger, smarter)
-ejší: for adjectives ending in -ý, -í (eg: harder, more expensive, nicer)
-ší: for some adjectives ending in -ký, -oký, -ný, -ní (e.g.: thinner, heavier, longer)
Irregular forms: good – better, bad – worse, tall – taller, etc.
Used with prepositions than or as (eg: more beautiful than you, as smart as him)
Superlative Form
The superlative form is used to describe the highest degree of a quality among three or more things. This is usually formed by adding the prefix nej- to the comparative form. For example:
- nejpomalejší (slower) from pomalejší
- nejkrásnější (more beautiful) from krásnější
- nejstarší (older) from starší
In Czech, there are several irregular comparative and superlative forms of adjectives and adverbs. These follow the typical pattern of adding suffixes like “-ší” or “ejší/-ější” for comparatives and “nej-” for superlatives, but the root of the word also changes.
Some examples of irregular forms:
- dobrý (good) – lepší (better) – nejlepší (best)
- špatný (bad) – horší (worse) – nejhorší (worst)
- velký (big) – větší (bigger) – největší (biggest)
- malý (small) – menší (smaller) – nejmenší (smallest)
- lepší (better) from dobrý
- větší (bigger) from velký
- menší (smaller) from malý
- nejlepší (best) from lepší
- největší (biggest) from větší
- nejmenší (smallest) from menší
