Conjugation I (-ę, -esz) in Polish

Overview

Conjugation I is one of the four main verb conjugation patterns in Polish. Verbs in this group take the endings -ę, -esz, -e, -emy, -ecie, -ą in the present tense. This is the largest conjugation class and includes many everyday verbs such as pisać (write), czytać (read), mieszkać (live), and pracować (work).

At the A1 level, learning Conjugation I gives you access to a huge number of common verbs. The pattern is highly regular, so once you know the endings you can conjugate dozens of verbs correctly. The main challenge is that many verbs undergo a stem change between the infinitive and the conjugated forms -- for example, pisać becomes piszę (not pisaę).

Understanding this conjugation pattern is the gateway to expressing actions, habits, and states in the present tense, which forms the bulk of beginner communication.

How It Works

Conjugation endings

Person	Singular	Plural
1st	-ę	-emy
2nd	-esz	-ecie
3rd	-e	-ą

Example: pisać (to write)

Person	Singular	Plural
1st	piszę	piszemy
2nd	piszesz	piszecie
3rd	pisze	piszą

Example: pracować (to work)

Person	Singular	Plural

2nd	pracujesz	pracujecie
3rd	pracuje	pracują

Stem changes

Many Conjugation I verbs have stem alternations. Common patterns:

• -ać → -ę with consonant change: pisać → pisz-, czytać → czyt-
• -ować → -uj-: pracować → pracuj-, kupować → kupuj-

Common Mistakes

Forgetting the stem change

• Wrong: Pisaę list.
• Right: Piszę list.
• Why: The infinitive stem pisa- changes to pisz- in conjugation. Always check the first person singular form.

Confusing -ować verbs

• Wrong: Pracowę w biurze.
• Right: Pracuję w biurze.
• Why: Verbs in -ować always change to -uj- before the personal endings.

Mixing up conjugation classes

• Wrong: Czytam książkę. (using Conj. IV endings)
• Right: Czytam is actually correct -- czytać happens to follow Conj. IV (-am, -asz). Check the first person form to determine the class.
• Why: The infinitive ending alone does not tell you the conjugation class. Always learn the 1st person singular form.

Usage Notes

Conjugation I verbs are used identically across all registers. There is no simplified or colloquial variant of the endings. The stem changes are consistent and apply in all contexts.

Practice Tips

1. For every new verb, learn the infinitive and the first person singular together: pisać (piszę), czytać (czytam), pracować (pracuję). The 1st person form reveals the conjugation class and any stem changes.
2. Group -ować verbs together and practice them as a set -- they all follow the same -uj- pattern.
3. Conjugate three new verbs per day through all six forms. Write them out by hand to reinforce the endings.
