Grammar rules

In Polish, adjectives are not static—they are dependent on the noun they modify. An adjective must agree with its noun in three specific categories:

Gender: Masculine, Feminine, or Neuter.
Number: Singular or Plural.
Case: Nominative, Genitive, etc.

Note: While English adjectives like "good" remain the same regardless of the noun, Polish adjectives must change their suffix to match the noun's grammatical attributes.

Declension / Conjugation patterns

Singular Nominative

The adjective follows the noun's gender. The "hard" ending for Masculine is -y, but if the stem ends in k or g, you must use -i.

Gender	Typical Noun Ending	Adjective Ending	Example
Masculine	Consonant	`-y` / `-i`	Nowy dom (New house)
Feminine	`-a`	`-a`	Nowa lampa (New lamp)
Neuter	`-o`, `-e`	`-e`	Nowe okno (New window)

Plural Nominative

Polish separates the plural into two distinct categories:

Virile (Męskoosobowy): Groups containing at least one male person. Adjectives use -y or -i, often with consonant mutations (e.g., r -> rz, k -> c).
Non-Virile (Niemęskoosobowy): Groups containing women, children, animals, or objects. The adjective ending is consistently -e (identical to Neuter singular).

Examples

Polish	English	Notes
Wysoki mężczyzna	A tall man	Masculine, ends in `-i` due to `k` stem.
Dobra kawa	Good coffee	Feminine, takes `-a` ending.
Małe dziecko	Small child	Neuter, takes `-e` ending.
Dobrzy studenci	Good students	Virile (mixed/male group), note `r` -> `rz` change.
Nowe telefony	New phones	Non-Virile, takes `-e` ending.

Common mistakes

The "Mężczyzna" Trap: Because mężczyzna (man) ends in -a, learners often mistakenly use feminine adjective endings. Remember: it is biologically masculine, so it requires masculine adjectives (Dobry mężczyzna).
K/G Spelling: Never write -ky or -gy. Polish orthography strictly requires -i after k and g (e.g., polski, długi).
Dziecko Gender: Dziecko (child) is grammatically Neuter. Use neuter adjective endings regardless of the specific child's gender (Moje dziecko).
False Friends: Some nouns have irregular genders (e.g., muzeum is neuter). Always verify the gender of new vocabulary rather than assuming based on the ending.

Watch out

Adjectives follow the noun's grammatical gender, not the biological gender. A male person is masculine, but a word like mężczyzna is a classic "trap" because its ending suggests feminine. Always learn the noun's gender along with the word itself.

Quick recap

Agreement is mandatory: The adjective is the noun's "shadow" and changes to match it.
Gender matters: Singular Masculine (-y/-i), Feminine (-a), Neuter (-e).
K/G Rule: Always use -i instead of -y after k and g.
Plural: Virile (mixed/male groups) uses mutated endings (-y/-i), while Non-Virile (everything else) uses a simple -e.
Cases: This logic of agreement extends to all cases (Genitive, Accusative, etc.), where both the noun and the adjective change based on their role in the sentence.
