põhiosast

Põhiosast is Estonian a noun meaning the main part or the principal component of something. The word is formed from the elements põh- (base, main) and osa (part). In use, põhiosa refers to the central or most important portion that determines the overall character or outcome of a project, document, system, or argument, as opposed to its secondary parts.

Grammatically, põhiosa can take forms such as põhiosast when used with prepositions to indicate “of the main part” or “from the main part.” It functions as a concrete noun in both everyday and formal language, and it is commonly paired with verbs or adjectives that describe centrality, importance, or scope. In many contexts, it is synonymous with terms like local core, central element, or main body, depending on the domain.

Usage and context examples illustrate its role in describing the essential content or structure. For instance, in a project report one might state that “projekti põhiosast kirjeldatakse peamised eesmärgid ja tehnilised nõuded,” signaling that the main part of the project documentation focuses on core goals and requirements. In academic writing, authors may refer to the põhiosast as the central section of an argument or analysis, distinguishing it from supplementary details.
