juoksussa

Juoksussa is a Finnish noun form meaning "in the act of running" or "in running." It is the inessive case of the noun juoksu, which denotes running as an activity or the sport of running. The base juoksu comes from the verb juosta, meaning "to run." The inessive suffix -ssa/-ssä marks location or state, so juoksussa literally translates to "in the running" or "in the act of running." In Finnish, juoksussa describes a person or thing that is currently engaged in running or in a running state.

Usage and nuance: juoksussa is a standard grammatical form used in sport contexts and everyday speech to indicate ongoing action related to running. It can describe a person who is actively running or a period during which running is taking place. It contrasts with other cases of juoksu, such as juoksua (partitive), juoksuun (illative), or juoksun (genitive).

Examples:

- Olen nyt juoksussa. (I am running right now / I am in the middle of a run.)

- Hän on juoksussa koko päivän. (He has been running all day.)

Related terms and compounds: juoksulenkki (a running jog / a short run), juoksukilpailu (a running competition), and juoksija (runner). The word appears across fitness, athletics, and travel contexts when describing running-related activity. In figurative language, juoksussa can convey being in motion or active, though the sense remains tied to running rather than a broader metaphorical “in progress.”
