neljapäeval
Neljapäeval is the Estonian adessive singular form of the noun neljapäev (Thursday). It is used to indicate the time when an action occurs, and is equivalent to the English expression “on Thursday.” The form appears in sentences to specify a single Thursday, such as in schedules or events.
Morphology and usage fall under the standard Estonian time expressions: neljapäeval denotes a specific day, while
- Kohtumeneljapäeval kell kaheksa. (We will meet on Thursday at eight.)
- Ta läks neljapäeval tööle. (He went to work on Thursday.)
- Nad reisivad neljapäevadel. (They travel on Thursdays.)
In normal prose, days of the week are lowercase in Estonian, so neljapäeval is written without capitalization
