öppnats

öppnats is the past passive participle of the Swedish verb öppna, meaning to open. It is used in passive constructions to indicate that something has been opened rather than describing an action performed by an agent. In present perfect passive, for example, dörren har öppnats means the door has been opened. The corresponding active past participle is öppnat, as in jag har öppnat dörren (I have opened the door).

In grammar, öppnats is formed with the past participle suffix -ts and is used with a finite auxiliary such as har or hade to express perfect or pluperfect passive. The related forms include opened in the present passive opens (öppnas) and the simple past passive opened (öppnades). Thus the pair öppnats and öppnades can convey different tense aspects in passive voice.

Usage notes: öppnats is common in written Swedish, especially in news reports, official announcements, and signage describing openings of facilities, shops, or events. The word is not a noun; it is a verb form. In headlines you may encounter bare forms like butiken har öppnats, or dörren öppnades, depending on tense.

Etymology: the form derives from the verb öppna plus the standard Swedish passive participle suffix -ts, a common pattern among -na verbs. See also öppna, öppnas, öppnades, and öppnat for related forms.
