Simultaanne

Simultaanne is a historical Dutch spelling associated with the concept of simultaneity, the state or quality of two or more events occurring at the same time. The form appears in older Dutch texts and grammars as part of early modern orthography, reflecting the period’s fluid spelling conventions. It is generally considered an archaic variant of the word family linked to simultaneous occurrence, and it is sometimes treated as an early form of the modern term simultaan or as an adjectival or nominal variant in context.

In usage, simultaanne appeared in philosophical, scientific, and musical writings to describe co-temporal relations or events that happen together. Its appearance illustrates how Dutch terminology for time-related concepts developed before standardization settled on contemporary spellings. As orthography stabilized over the 18th and 19th centuries, the form fell from regular use, and modern Dutch typically expresses the idea with gelijktijdigheid (the noun) or with more common forms related to simultaan in compound phrases.

Today, simultaanne is mainly of interest to linguists, philologists, and historians of science as an example of historical spelling variation and the evolution of Dutch vocabulary for temporal concepts. The modern equivalents for expressing the concept are gelijktijdigheid and, in adjectival or compound contexts, the contemporary form related to simultaan. For readers seeking related concepts, sources on simultaneity in philosophy, physics, and music provide the current terminology.
