Masculine-Personal Plural Accusative

In Polish, the Accusative case is used for direct objects. However, the plural forms depend on the 'gender' of the group. Unlike the singular, where 'animate' includes animals, the plural 'personal' category is primarily for male humans, though it also includes personified entities like gods, angels, and devils.

1. The Rule of Syncretism
For masculine-personal groups (men, or groups with at least one man), the Accusative plural is the same as the Genitive plural. For all other groups (women, children, animals, objects), the Accusative is the same as the Nominative.

2. Noun Endings
Nouns typically take one of these endings:

• -ów: The most common ending for most masculine stems (e.g., studentów, panów), including many that end in -a in the singular (e.g., kolegów, dentystów).
• -i / -y: Used for soft and hardened stems. Use -i after soft consonants (like l, j, ś, ć, ń; e.g., nauczycieli, gości) and -y after hardened consonants (like rz, sz, cz, ż; e.g., lekarzy, graczy).
• Zero ending (ø): Used for a specific subset of masculine-personal nouns, most notably przyjaciół (from przyjaciel), książąt (from książę), and as a rare exception for nouns ending in -a, mężczyzn (from mężczyzna). Note that most masculine-personal nouns ending in -a take -ów instead.

3. Good News: No Consonant Mutations!
Unlike the Nominative plural, which often requires tricky consonant changes (e.g., Polak becomes Polacy), the Accusative plural avoids these. You generally just add the ending to the base stem (e.g., Polaków). However, keep in mind that vowel shifts or the dropping of a fleeting 'e' can still occur (e.g., chłopiec becomes chłopców, ojciec becomes ojców). This still makes it much easier to form!

4. Adjective and Pronoun Endings
Adjectives and adjectival pronouns (like tych, moich) take the endings -ych or -ich, matching the Genitive plural agreement. Personal pronouns have their own specific forms (e.g., oni becomes ich, my becomes nas).

5. The 'One Man' Rule
If a group contains 100 people and only one of them is a man, the entire group is grammatically masculine-personal. You must use these endings for the whole group.

6. Special Cases and Exceptions

• Irregular nouns: The most common masculine-personal plural noun is ludzie (people), which becomes ludzi in the Accusative. Other highly common irregulars include brat (brother) becoming braci, and ksiądz (priest) becoming księży.
• Numerals: Numbers 2-4 must also agree with this case (e.g., dwóch, trzech). For numbers 5 and above (e.g., pięciu, dziesięciu), the numeral technically forces the noun into the Genitive case anyway, though the visible result is exactly the same.
• Depreciative forms: Pejorative or depreciative forms of masculine-personal nouns (e.g., pijaki, chłopy) are treated as non-masculine-personal, so their Accusative matches the Nominative.

Nouns in -anin: The singular segment -in- disappears in the plural: Rosjanin → Rosjanie → widzę Rosjan (a Russian man → Russian men → I see Russian men). The ending is lexical: Amerykanin → Amerykanie → znam Amerykanów (an American man → American men → I know American men). Do not add -ów to every -anin noun or retain -in- in its plural.
