võitluse
Võitluse is the genitive singular form of the Estonian noun võitlus, which means struggle, fight, or battle. The base võitlus comes from the verb võitlema (to fight) with the suffix -lus, forming a noun that denotes an action, process, or state. As a grammatical form, võitluse signals possession or relation and is used to link other words to the idea of a struggle, for example võitluse ajal (“during the struggle”) or võitluse teooria (“the theory of the struggle”).
In usage, võitluse appears mainly in compound nouns and noun phrases that name particular struggles. Common
Note that võitluse itself is not a standalone lexical item with a separate meaning beyond this genitive
