Kütusega

Kütusega is an Estonian word form of the noun kütus (fuel) in the instrumental/comitative case. It denotes the means or material used to perform an action, or something that accompanies the subject. In English it corresponds to “with fuel” or “using fuel.” The form is common in technical, mechanical, and everyday contexts where fuel is the source of power or the substance involved.

Grammatical notes: In Estonian, the instrumental/comitative case is formed by adding -ga to the noun stem. For kütus, this yields kütusega. This form answers questions such as millega? (with what?) or kütustega? in plural contexts. The word kütusega typically appears alongside verbs of activity or states that describe powered operation, fueling, or energy source. The associated genitive and other cases of kütus are kütuse (genitive), kütusest (ablative/inessive-related forms), kütuses (inessive), and kütusesse (illative), illustrating the word’s full inflection in Estonian.

Usage: Kütusega is widely used in both everyday and formal language. Common usages include describing powered devices or vehicles, for example, Auto töötab kütusega (The car runs on fuel). It can also appear in discussions of fuel systems, energy sources, or logistics, such as kütusevaru (fuel supply) or kütusega seotud küsimused (fuel-related questions). In many contexts, more neutral alternatives like “kütusega kasutatav” (usable with fuel) or “kütuse abil” (with the help of fuel) may be chosen for stylistic reasons.
