ustalaj

Ustalaj is a Polish verb form that functions as an imperative. It is the second-person singular imperative of the verb ustalać, which means to determine, establish, or set. The action described by ustalać is typically ongoing or repeated in imperfective usage, while its perfective counterpart ustalić conveys a completed establishment or decision.

In usage, ustalaj is used to instruct someone to determine or fix a parameter, condition, or plan. It is common in professional, administrative, and collaborative settings, where clear decisions and specifications are required. The form can appear with various objects, such as warunki (terms), priorytety (priorities), koszty (costs), or harmonogram (schedule).

Examples of the imperative include:

- Ustalaj, jakie będą koszty projektu. (Determine what the project costs will be.)

- Ustalaj priorytety na dzisiejszy dzień. (Set the priorities for today.)

- Ustalaj kolejność kroków w instrukcji. (Determine the order of steps in the instruction.)

Grammatically, ustalaj denotes an instruction directed at a single informant, though parallel forms exist for different persons: ustalajcie is the plural form, used to address a group, and ustalajmy can express a suggestion or command including the speaker, as in “Let us determine.” As a word, ustalaj is part of a larger family around establishing conditions and criteria, with related nouns such as ustalenie (an establishment or determination) and related verbs like ustalać and ustalić in their respective aspects.
