lisäystä

Lisäystä is a Finnish noun referring to an addition, increase, or supplement added to something else. It is the partitive singular form of lisäys, the noun that denotes the act or result of adding. The base lisäys comes from the verb lisätä, “to add,” with the nominalizing suffix -ys. Related forms include lisäyksen (genitive singular), lisäykset (nominative plural), and lisäyksiä (partitive plural). The word is used across contexts to denote an extra amount, content, or component.

Usage and examples are common in everyday and formal language. In financial or planning contexts it can mean extra funding or an additional item in a budget, for example: Tarvitsemme lisäystä budjettiin. In dietary or nutrition discussions it can refer to adding components to a regimen: Lisäystä ruokavalioon kannattaa tehdä varoen. In military or organizational contexts it may describe additional personnel or resources arriving: Lisäystä lähetettiin joukkoihin. The partitive form lisäystä is typically used when the amount or portion is indefinite or not yet completed.

See also terms in related semantic fields include lisätä (to add), täydennys (completion or supplementation), and lisäaine (additive in food). Lisäys as a noun is distinct from these but shares the same root, and its exact meaning is determined by context and grammatical case.
