ollaverbillä

Ollaverbillä is a label encountered in some Finnish language-learning and linguistic resources to describe the use of the verb olla (to be) as a main verb or as an auxiliary in Finnish grammar. The term is not part of the official Finnish grammar framework, but it is used heuristically to highlight how olla functions across different sentence types.

In standard Finnish, olla serves two primary roles. As a copula, it links the subject to a predicative expression, as in Hän on opettaja (He is a teacher). As an auxiliary, olla combines with a participle or a verbal form to convey aspect or perfect tenses, as in Olen syönyt (I have eaten) or Olin nähnyt (I had seen). The olla-auxiliary can also appear with progressive or prospective readings in combinations such as Olen lukemassa kirjaa (I am in the process of reading a book).

The usage category often referred to under ollaverbillä includes these functions: treating olla as a finite auxiliary in compound tenses, using olla to express current or ongoing action in combination with a present participle-like form (for example, lukemassa), and employing olla in copular sentences that express identity or quality. The exact terminology and scope vary between grammars and teaching materials, and some references may simply describe these as standard uses of the auxiliary verb olla rather than a distinct grammatical class.

Overall, ollaverbillä is best understood as a pedagogical shorthand for analyzing how the Finnish be-verb operates in combination with other verbs to convey tense, aspect, and predication. It is less a formal category in reference grammars than a practical label used in some explanatory texts. See also olla, Finnish copula, and Finnish auxiliary constructions.
