Koopen

Koopen is a historical Dutch verb that functioned as the infinitive meaning to purchase or to buy. In contemporary Dutch, the corresponding verb is kopen, and koopen is now primarily found in older texts, linguistic descriptions, or discussions of the language’s history rather than in everyday speech.

Historical context and usage

Koopen appears in Early Modern Dutch and earlier orthographies. The form reflects older spelling conventions in which the infinitive could be written with the ending -en in a broader set of verbs than is common today. In surviving quotations and legal or mercantile documents from past centuries, koopen often appears in phrases equivalent to modern te kopen, such as te koopen or om te koopen, serving the same grammatical role as the modern infinitive.

Orthography and standardization

The shift from koopen to kopen occurred gradually as Dutch spelling was standardized, with reforms in the 17th through 19th centuries favoring the streamlined modern form kopen. Today koopen is typically encountered only in historical editions, philological notes, or dialect descriptions that discuss older spellings.

Etymology

Koopen shares its root with the modern verb kopen; the distinction is primarily orthographic rather than semantic. The meaning—to purchase—remains the same, but the preferred spelling in standard modern Dutch is kopen.
