öljyittäin
öljyittäin is a Swedish adverb that translates to "oily" or "greasily" in English. It describes a manner of being or acting that is characterized by the presence or application of oil or grease. This can refer to a physical state, such as a surface that is oily to the touch, or a more metaphorical sense, implying a smoothness or slipperiness in a process or behavior.
For instance, one might describe a machine part as functioning öljyittäin if it has been adequately lubricated.
