perusnimeä

Perusnimeä is the partitive singular form of the Finnish noun perusnimi, a term that denotes the base name or canonical form of a noun or proper name. In linguistic and onomastic discussion, perusnimi refers to the dictionary or lemma form from which all inflected variants are derived. The concept is akin to the lemma used in many languages and is central to tasks such as lemmatization, name normalization, and data indexing.

In practice, the base form marked by perusnimi or its related term perusmuoto is the form that appears in dictionaries and linguistic analyses. When a name is studied or stored in databases, this canonical form serves as the stable reference point. For example, the base form of the city name Helsinki is Helsinki; its inflected forms include Helsingin (genitive) and Helsinkiä (partitive), among others. The word perusnimeä would be the partitive singular form of perusnimi, used in sentences that require a partial or object-oriented construction.

The term perusnimeä is primarily a grammatical and descriptive label rather than a widely used technical category in standard Finnish grammar, where perusnimi or perusmuoto are more common. In fields such as computational linguistics, linguistics, and information science, the idea behind perusnimi remains important as a reference form for accurate name parsing, normalization, and indexing.
