tühistatakse

Tähistatakse is the passive present form of the Estonian verb tähistama, meaning to celebrate, mark or commemorate. In this form, the phrase translates as "is celebrated" or "is being celebrated" and is used to indicate that an event, date or milestone is observed, often publicly or officially.

Grammatically, -takse is a passive suffix that forms the Estonian present passive. The subject may be omitted or expressed later; time phrases such as "24. veebruaril" or "järgmisel nädalal" indicate when the celebration occurs. Example: "Iseseisvuspäeva tähistatakse 24. veebruaril" – "Independence Day is celebrated on February 24."

Usage: Tähistatakse is common in news, calendars, and formal writing for national holidays, anniversaries, and cultural or ceremonial events. The term carries a neutral to formal tone; it often denotes an official or widely observed observance rather than private celebration.

Etymology and related terms: The verb tähistama derives from tähis, meaning sign or mark; to tähistada is to mark something as significant. Related noun is tähistamine, meaning the act of celebrating or marking; related concepts include pidustused (festivities) and mälestamine (remembrance).
