In short

Polish has one past tense, and it works for both English “I read” and “I was reading” - aspect (Lesson 20), not a separate tense, tells you whether the action was finished. What makes the Polish past unusual is that the verb form agrees with the gender of the subject (a man and a woman say the past differently) and that the personal endings are mobile: the little -m, -ś, -śmy, -ście can slide off the verb and hook onto an earlier word. Master those two things and the whole tense falls into place.

The rule

The past tense is built on the l-participle (sometimes called the l-form), not on the present stem. For most verbs you take the infinitive, drop -ć, and add a gendered suffix:

• -ł for masculine singular: czytał (he read)
• -ła for feminine singular: czytała (she read)
• -ło for neuter singular: czytało (it read)
• -li for the virile plural (any group that includes at least one male person): czytali
• -ły for the non-virile plural (everything else - women, children, animals, things): czytały

Gendered l-forms

Unlike the present tense, the Polish past shows the subject’s gender. A single English “I read” therefore has two Polish forms: a man says czytałem, a woman says czytałam. The same split runs through ty and through the plural, where the key contrast is virile vs non-virile (see Lesson 30): oni czytali (men, or a mixed group) versus one czytały (women/things).

Mobile personal endings

The l-participle already shows gender and number, but for the 1st and 2nd person you must also add a personal ending:

• 1sg -m, 2sg -ś, 1pl -śmy, 2pl -ście.
• The 3rd person has no personal ending at all - the bare l-form był / była / byli already means “he/she/they was/were”.

These endings are clitics: they are not glued to the verb. In neutral order they sit on the verb (czytałem), but they can detach and jump onto the first stressed word of the clause - a question word, a conjunction, an emphasised pronoun:

• Gdzie byłeś? -> Gdzieś był? (Where were you?)
• Dlaczego nam nie powiedziałeś? -> Dlaczegoś nam nie powiedział?
• Co ty robiłeś? -> Co tyś robił? / Coś robił?

This is optional and stylistic, but it is everywhere in speech and writing, so you must be able to recognise it. One firm rule: the ending is written as one word with its host (gdzieś, dlaczegoś, tyś), and it never lands on the negation nie.

Vowel change in -eć verbs

Verbs whose infinitive ends in -eć shift e -> a in the singular and the non-virile plural, but keep e (as i/e) in the virile plural: mieć -> miałem, miał, miała, miało, miały but mieli. The same pattern hits widzieć (widział / widzieli) and słyszeć (słyszał / słyszeli).

Forms & patterns

Personal endings of the past tense (l-form + ending; 3rd person adds nothing):

Note the connecting -e- in the masculine singular (czytał-e-m, czytał-e-ś); the feminine and plural forms attach the ending straight onto the vowel (czytała-m, czytały-śmy).

Full paradigm - regular czytać (to read, imperfective):

The verb być (to be) - the model for all past forms:

A perfective verb - zrobić (to do, once/completed): same endings, aspect gives “did / got done”.

Consonant/vowel alternations to expect (the l-form is not always infinitive minus -ć):

Examples

Common mistakes

• ja byłem said by a woman -> byłam - the l-form must match your own gender.
• oni czytały (group with a man) -> czytali - a group that includes a male person is virile (-li).
• czytałm -> czytałem - the masculine 1sg needs the linking -e- before -m.
• niem widział / niem widział -> nie widziałem - the ending never attaches to nie; keep it on the verb.
• gdzie byłeś -> writing gdzieś był as two words gdzie ś był -> gdzieś był - the clitic is written together with its host.
• miałem used for “they (men) had” -> mieli - the virile plural of mieć keeps -e- (mieli), not -a-.
• mogł for “he could” -> mógł - the bare masculine form keeps ó; the vowel is o only once an ending follows (mogłem, mogła, mogli).

Tips

• Learn every new verb’s past by its three anchors: był / była / byli. From those you can rebuild the whole table.
• Tie the -m / -ś / -śmy / -ście endings to the present-tense persons you already know: same “I / you / we / you-all” markers, just movable.
• The plural boils down to one question: is there a male human in the group? Yes -> -li; no -> -ły.
• When a sentence starts with a question word (gdzie, dlaczego, co) or że, expect the personal ending to have jumped onto it: gdzieś, dlaczegoś, coś, żeś. Careful: gdzieś and coś are also everyday words for “somewhere” and “something” - the rest of the sentence tells you which one you have.
• Only 1st and 2nd person carry an ending; if you see a bare był, robiła, poszli, the subject is automatically he / she / they.
