Future Tense

The Polish future tense is split into two distinct structures based on aspect:

1. The Perfective Future (Completed Actions)
To express a single, completed event or an achieved result in the future, use a perfective verb. There is no auxiliary verb. You simply attach standard present-tense personal endings directly to the perfective verb stem (e.g., zrobię). Perfective verbs fall into the exact same conjugation groups as present-tense verbs (like -ę/-esz, -ę/-isz, or -am/-asz), so there are no new ending patterns to learn. Because perfective verbs describe completed actions, they cannot happen in the present moment, so applying these endings automatically projects the meaning into the future.

2. The Imperfective Future (Ongoing/Repeated Actions)
To express an ongoing process, a continuous state, or a habitual action in the future, use an imperfective verb. This is a compound tense requiring the future forms of być (będę, będziesz, będzie...) plus one of two options:

• The infinitive of the main verb (e.g., będę robić). This form is fully standard and acceptable in all registers, both written and spoken. As a modern usage tip, it is also gender-neutral, which is useful when the subject's gender is unknown or when a speaker wishes to remain gender-neutral.
• The 3rd-person past tense (l-participle) of the main verb, which must agree with the subject in gender and number (e.g., singular: będę robił / będę robiła; plural: będziemy robili / będziemy robiły). This form is extremely common and perfectly natural in everyday spoken Polish, often used more frequently than the infinitive, as well as being standard in formal and written contexts. Note that the plural forms require you to choose between the masculine-personal form (robili, for groups with at least one male) and the non-masculine-personal form (robiły, for all other groups).

3. The Future of Być
Note that być (to be) is the only imperfective verb that forms a simple, one-word future tense (e.g., będę gotowy). It does not use an auxiliary verb.

Note on Modal and Motion Verbs: For modal verbs (like musieć, chcieć, móc), it is strongly preferred and considered standard to use the past l-participle form (e.g., będę musiał/musiała) rather than the infinitive. While you might hear the infinitive in casual speech, it creates a clunky 'double infinitive' when another verb follows (e.g., będę musieć czekać) and is generally avoided in careful speech. Similarly, determinate verbs of motion (like iść or jechać) heavily favor the l-participle form (e.g., będę szedł) over the infinitive (będę iść), which can sound awkward to native speakers.
