regulaatorist

Regulaatorist is the elative singular form of the Estonian noun regulaator, meaning regulator (either a person who regulates or a device that regulates). As a grammatical form, regulaatorist does not constitute a separate concept; its meaning depends on context. It is used to express origin or source (from the regulator) and, in certain constructions, to indicate the topic of discussion (about the regulator).

In usage, examples include regulaatorist tulenev mõju, meaning “the influence arising from the regulator,” and arutelu regulaatorist, understood as “a discussion about the regulator.” The exact interpretation depends on the surrounding words and the intended sense of origin or topic.

Etymology and formation: regulaator is a loanword in Estonian, commonly arising in technical and administrative language and typically linked to the English or German word regulator, itself from Latin regula “rule” with an agent suffix. The elative form regulaatorist is formed by adding the elative suffix -st to the stem regulaator, with standard Estonian orthographic adjustments.
