Allrektsioon

Allrektsioon is a term that appears in a limited range of Estonian-language technical texts. There is no universally accepted definition across disciplines. In some usages, allrektsioon refers to a reaction process in which many components of a system participate simultaneously in a single event, rather than through a sequence of discrete steps. Because the term is not standardized, its meaning can vary depending on author and field.

Because attestation is sparse, the term is often encountered as a neologism or translator’s coinage rather than as a settled concept. In chemistry and related theoretical contexts, it may be used to describe holistic or concerted transformations, but such uses are informal and not part of a formal theory. Readers should consult the original source to understand how the author defines allrektsioon in that instance.

Etymology and status: The word appears to be a composite of Estonian all- , meaning “all,” and rektsioon, meaning “reaction,” mirroring the familiar English construction but without a standardized meaning. It is not listed in major Estonian dictionaries and remains regional or specialist. If you have a specific field, publication, or definition in mind, that context would help clarify the intended sense of allrektsioon.
