lisandumisest

Lisandumisest is an Estonian linguistic term referring to the genitive form of lisandumine, the noun that denotes the act or process of adding. In this sense, lisandumisest means “of the addition” or “from the addition” and is used in formal or technical language to discuss additions as a concept, source, or consequence.

Etymology and form: lisandumine is a deverbal noun formed from lisand (additive, supplement) and the -mine nominalization, meaning the act of adding. The form lisandumisest is a case-inflected variant used to express possession, origin, or relatedness to the act of adding, similar to other Estonian nominalized constructions.

Usage: The term occurs in contexts where an addition plays a functional or causal role. It can appear in legal, scientific, or analytical prose when describing changes introduced by adding elements, amendments, or supplements. An example in English would be “the effect arising from the addition,” which in Estonian would be rendered through lisandumisest, for instance in phrases discussing lisandumisest tulenev mõju (the effect arising from the addition). The expression helps to specify that a described phenomenon is tied to the act of adding rather than to the added item itself.
