The Polish personal pronouns decline through all six cases — but several of them have two or three forms for the same case, and choosing between them is one of the most persistent low-level errors English speakers make. Ja alone offers mnie, mi, and mną; on offers jego, go, and niego for one and the same accusative slot. The forms are not interchangeable. There is a long, stressed form for emphasis, clause-initial position, and (with an n-) after prepositions; and a short, unstressed clitic for ordinary, neutral position. "I see him" is widzę go, but "I see him (not her)" is widzę jego, and "for him" is dla niego. Get this right and your Polish stops sounding like a textbook.
The full table
The long/stressed forms are listed first, the short clitics in bold, and the n- (post-preposition) forms last where they exist.
| Case | ja | ty | on (m.) / ono (n.) | ona (f.) |
|---|---|---|---|---|
| nominative | ja | ty | on / ono | ona |
| genitive | mnie | ciebie / cię | jego / go / niego | jej / niej |
| dative | mnie / mi | tobie / ci | jemu / mu / niemu | jej / niej |
| accusative | mnie | ciebie / cię | jego / go / niego (on); je / nie (ono) | ją / nią |
| instrumental | mną | tobą | nim | nią |
| locative | mnie | tobie | nim | niej |
And the plurals — these have no clitic split; each case is a single form:
| Case | my | wy | oni (m.-pers.) / one (other) |
|---|---|---|---|
| nominative | my | wy | oni / one |
| genitive | nas | was | ich / nich |
| dative | nam | wam | im / nim |
| accusative | nas | was | ich / nich (oni); je / nie (one) |
| instrumental | nami | wami | nimi |
| locative | nas | was | nich |
Don't try to memorise this as a wall of forms. Memorise the three rules below, and the table becomes predictable.
Rule 1 — the clitic is the default, neutral form
In an ordinary sentence, where you're not stressing the pronoun, use the short clitic: go, mu, cię, ci, mi, ją. It's unstressed and leans on the neighbouring word. This is the form you'll use 90% of the time in speech.
Widzę go codziennie w autobusie.
I see him every day on the bus. (neutral → clitic go)
Dałem mu klucze i poszedłem.
I gave him the keys and left. (neutral → clitic mu)
Kocham cię.
I love you. (the clitic cię is the normal form here)
The clitics that exist are: go, mu (for on/ono), cię, ci (for ty), mi (dative of ja), and ją (accusative of ona — its only short form). Note there is no short genitive/accusative for ja: it's always mnie. And there is no clitic *mię in the modern language — mnie covers both the stressed and neutral roles for "me."
Rule 2 — the long form is stressed, emphatic, and clause-initial
Use the long form (jego, jemu, ciebie, tobie, mnie as a stressed word) when the pronoun carries emphasis or contrast, or when it stands first in the clause. Clitics are unstressed by nature, so they physically cannot bear stress or open a sentence — the long form steps in.
| Neutral (clitic) | Emphatic / initial (long) |
|---|---|
| Daj mi to. "Give it to me." | Mnie to daj, nie jemu. "Give it to me, not him." |
| Widzę go. "I see him." | Jego widzę, jej nie. "I see him, not her." |
| Powiedziałem ci. "I told you." | Tobie powiedziałem pierwszej. "I told you first." |
Mnie nie pytaj, ja nic nie wiem.
Don't ask me — I don't know anything. (stressed + clause-initial → mnie, not the clitic)
Jego zaprosili, a o mnie zapomnieli.
They invited him, and forgot about me. (contrast → jego)
Rule 3 — after a preposition, use the n-form (and never the clitic)
This is the rule English speakers break most. After any preposition, the third-person pronouns take a special form beginning with n-: niego, niemu, niej, nim, nich, nimi, nie. The clitics (go, mu, ją) are banned after prepositions, and the bare long forms (jego, jemu) are too — it must be the n- form.
| Without preposition | With preposition → n-form |
|---|---|
| widzę go "I see him" | dla niego "for him" (not *dla go, not *dla jego) |
| dałem mu "I gave him" | ku niemu "towards him" |
| znam ją "I know her" | o niej "about her", z nią "with her" |
| pytam ich "I ask them" | do nich "to them", z nimi "with them" |
Why does this exist? Historically the n- is a fossil of an old preposition that ended in a nasal consonant; that final n detached from the preposition and re-attached to the front of the following pronoun. You don't need the history — just internalise that preposition + 3rd-person pronoun = n-form. The 1st and 2nd person pronouns (mnie, tobie, nami…) have no n- form; they keep their long form after prepositions (do mnie "to me," z tobą "with you").
Czekałem na nią godzinę pod kinem.
I waited for her for an hour outside the cinema. (na + nią, the n-form)
Bez niego nie zaczynamy zebrania.
We don't start the meeting without him. (bez + niego)
Rozmawialiśmy o nich cały wieczór.
We talked about them all evening. (o + nich)

Minimal pairs — the difference you can hear
The three forms genuinely change the meaning or the emphasis. Compare:
| Sentence | Form | Effect |
|---|---|---|
| Daj mi to. | clitic mi | "Give it to me." (neutral) |
| Mnie to daj. | stressed mnie, fronted | "Give it to me (not someone else)." |
| Daj to dla mnie. | — | wrong verb government, but note: after a preposition you must use mnie, never a clitic |
— Komu mam to dać? — Mnie! Mnie daj!
— Who should I give it to? — Me! Give it to ME! (stressed, and clause-initial → mnie)
Powiedz mu, że dzwoniłam.
Tell him I called. (neutral clitic mu)
Jemu nic nie mów, on wszystko wygada.
Don't tell him anything — he blabs everything. (contrast + initial → jemu)
The clitic's place in the sentence — second position
Because clitics are unstressed, they don't just sit anywhere — they gravitate to second position in the clause, often jumping ahead of the verb. Już ci mówiłem "I already told you," not *Już mówiłem ci in neutral speech. Several clitics can cluster, in a fixed order. The mechanics are detailed on the clitics and second position page; for now, just know that a short pronoun likes to slide leftward toward the front of the clause.
Wczoraj ci to tłumaczyłem, już nie pamiętasz?
I explained it to you yesterday, don't you remember already? (clitics ci + to cluster early)
Common Mistakes
❌ Dla go to zrobiłem.
Incorrect — a clitic can't follow a preposition; use the n-form
✅ Dla niego to zrobiłem.
I did it for him.
After a preposition you must use the n-form niego — never the clitic go, and never the bare jego.
❌ Go nie znam.
Incorrect — a clitic can't open a sentence
✅ Jego nie znam.
Him, I don't know. / I don't know him. (fronted, emphatic)
A clitic cannot stand clause-initially. To front the pronoun, switch to the long form jego. (Neutral order would be Nie znam go.)
❌ Kocham ciebie. (as a plain 'I love you')
Marginal — the neutral form is the clitic cię
✅ Kocham cię.
I love you.
For a plain "I love you," use the clitic cię. Kocham ciebie is not ungrammatical, but it stresses "you" — "it's you I love" — so it sounds pointed unless that's what you mean.
❌ Daj mnie spokój.
Incorrect — neutral dative of 'ja' here is the clitic mi
✅ Daj mi spokój.
Leave me alone. (lit. 'give me peace')
In neutral position the dative clitic is mi. Mnie is the stressed/clause-initial dative — fine in Mnie daj spokój "leave me alone," but not in the unstressed default.
❌ Idę do jego jutro.
Incorrect — after a preposition the genitive is the n-form niego
✅ Idę do niego jutro.
I'm going to his place tomorrow.
Do governs the genitive, and a 3rd-person pronoun after a preposition is the n-form: do niego, not *do jego or *do go.
Key Takeaways
- Many pronouns have a long stressed form and a short clitic: mnie/mi, ciebie/cię, tobie/ci, jego/go, jemu/mu, ją (clitic only).
- Default to the clitic (go, mu, cię, ci, mi, ją) in neutral, unstressed position.
- Use the long form (jego, jemu, ciebie, tobie, mnie) for emphasis, contrast, and clause-initial position — a clitic can never open a sentence.
- After any preposition, 3rd-person pronouns take the n-form: niego, niemu, niej, nim, nich, nimi, nie — never a clitic, never the bare jego/jej.
- 1st/2nd person have no n- form: do mnie, z tobą, o nas keep their long form after prepositions.
