dziennie

Dziennie is a Polish adverb meaning daily or per day, used to indicate how often something happens or the amount assigned to a single day. It is formed from the noun dzień (day) with the adverbial suffix -nie and is typically used with verbs or with numbers to express per-day quantities.

In everyday language, codziennie is the more common synonym for “every day,” while dziennie tends to appear in formal, technical, or statistical contexts, especially when describing per-day rates, costs, or counts. The adjective dzienny exists as a related term describing something related to a day or a daily measure, as in phrases like koszty dzienne (daily costs) or dochód dzienny (daily income).

Examples of usage include: Dziennie piję dwa litry wody. Pociąg kursuje dziennie cztery razy. In contrast, you might encounter dzienny as part of a noun phrase such as koszt dzienny or wydatki dzienne, where the meaning shifts from per-day action to a per-day quantity or rate.

Etymology traces dziennie to the noun dzień (day) with the suffix -nie, forming an adverb that conveys repetition or allotment on a day-by-day basis. See also codziennie (every day) and dzienny (daily, relating to a day) for related usage and nuance.
