kaasulla

Kaasulla is a Finnish adessive form of the noun kaasu, meaning gas. In linguistic terms it denotes means or instrumentality, translating roughly to “with gas” or “on gas.” In everyday language it is used to describe both energy sources for devices and vehicles, as well as the manner of operation, such as acceleration.

As a grammatical form, kaasulla is formed by adding the adessive suffix -lla to the noun kaasu. It appears in contexts where gas is the energy source (for example, a vehicle powered by gas) or where gas is the means of operation (for instance, pressing the accelerator). The meaning can be literal, referring to natural gas, gas-powered machinery, or other gas-based energy, or figurative, reflecting the idea of rapid acceleration or aggressive operation.

Usage notes and context: kaasulla is commonly found in automotive discussions, energy reporting, and technical writing, as well as in colloquial speech. It is often contrasted with other instrumental forms such as bensiinillä (gasoline), sähköllä (electric power), or dieselillä (diesel). In idiomatic use, kaasulla can also convey a sense of speed, similar to the English phrase “on the gas.”

Examples:

- Auto toimii kaasulla. (The car runs on gas.)

- Hän kiihdytti kaasulla. (He accelerated, literally on the gas.)

- Tämä laite toimii kaasulla, ei sähköllä.

Kaasulla is not a standalone proper noun; it is a grammatical expression tied to the noun kaasu and its use as the energy source or mode of operation. See also kaasu, bensiinillä, sähköllä, and the broader discussion of Finnish adessive case usage.
