Siepen

These words often form a part of placenames especially in the area from the central and southern Ruhrgebiet southwards as far as southern Westphalia (Sauerland), as well as in the adjacent regions of Bergisches Land, Siegerland and southern Rhineland. In North Hesse the term is found in the old Lower Saxon dialect area in the counties of Waldeck-Frankenberg to Korbach and Bad Arolsen. The word is derived from the Middle Low German word sîpe "wet depression" or "little stream, brook", the verb sîpen means "trickle, drip". Grammatically siepen has a neuter or masculine gender. The word forms Siefen and Seif are common in the Franconian and Hessian region. The form -siepen (with a p) as part of the name of waterbodies or places is, by contrast, mainly found in the northern Bergisches Land as far as south Westphalia. The difference in spelling reflects dialect differences which arose as a result of a strong phonetic shift; the region in which this occurs is where the dialect boundary of the so-called Rhenish Fan runs. The headstreams in the valley do not carry water all year round; but have nonetheless carved out the V-shaped valley.
