About Adjectives

Adjectives are a flexible part of speech. They indicate properties of nouns and possessive relationships.

There are three main groups of adjectives:
hard, soft, and possessive

Soft adjectives:
Soft adjectives end with "-Í"

The forms of the soft adjectives in the masculine, feminine, and neuter are exactly the same.
(cizí muž - a foreign man, cízí žena - a foreign woman, cizí dítě - a foreign child, cizí muži - foreign men, cizí ženy - foreign women, cízí děti - foreign children)

Hard adjectives:
Hard adjectives always change their form according to the gender and number of the noun.

Hard adjectives end with:
(for singular - plural)
masculine: Ý - Í
feminine: Á - É
neuter: É - Á

Possessive adjectives:
They say something or someone belongs to something or someone.
