köken: Derived from থান (than, “place”) which is from Magadhi Prakrit 𑀣𑀸𑀦 (thāna), from Sanskrit स्थान (sthāna), from Proto-Indo-Iranian *stáHnam, from Proto-Indo-European *stéh₂-no-m, from *steh₂- (“to stand”). Compare Hindi थाना (thānā) and Urdu تھانہ. Doublet of ঠাঁই (ṭhãi).
Potentially attested as post in 1388, attested with certainty as uetpost in 1418. Calque of West Frisian Bûtenpost, a compound of Old Frisian buta (“outer, seaward”) and post (“simple bridge, gangboard across a ditch”). The element buiten was added to distinguish the settlement from Lutkepost.
