Vuorokaudella

Vuorokaudella is a Finnish adverbial form derived from vuorokausi, meaning a 24-hour day. It is used to express how often or when something occurs within a single day, typically indicating frequency or timing over a 24-hour period. In practical language, similar meanings are conveyed with phrases using vuorokaudessa, but vuorokaudella appears in some contexts and registers as a variant of that time frame.

Etymology and form: The base vuorokausi denotes a 24-hour period. The suffix -lla marks the adessive case in Finnish, yielding vuorokaudella to signal “on/in a 24-hour day” or “within a day.” This contrasts with the inessive form vuorokaudessa, which emphasizes being inside the 24-hour period. The choice between forms can reflect subtle nuances of time expression or stylistic preference.

Usage: Vuorokaudella is most commonly encountered in prescriptions, scheduling, and statistical or descriptive text where a daily time frame is being specified. A typical, more common construction in everyday Finnish is using vuorokaudessa: e.g., “kaksi kertaa vuorokaudessa” for “twice per day.” Vuorokaudella may appear in older sources, regional speech, or more formal/technical writing, where the emphasis is on the time span as something that occurs within a day rather than simply per day.

Related terms include vuorokausi (the 24-hour period) and the broader concept of time-based frequency expressions in Finnish. Understanding the distinction between vuorokaudella and vuorokaudessa helps in selecting the appropriate form for precise, context-appropriate time references.
