köken: From Middle High German tamm. Probably via Old High German *tamm from Proto-Germanic *dammaz, though it is sometimes considered a later back-formation from the verb dämmen. The modern consonantism is Central and Low German (compare Middle Low German dam).
köken: Inherited from Middle French digue, from Old French dike, diic, from Middle Dutch dijc (compare modern Dutch dijk), from Old Dutch diic, dīc, from Frankish *dīk, from Proto-Germanic *dīkaz (“pool”), from Proto-Indo-European *dʰeygʷ- (“to stick, stab, pierce, dig”). More at dig, dike, ditch.
dam (a structure placed across a flowing body of water to stop the flow or part of the flow) · impediment, obstacle · hurdle (an artificial barrier, variously constructed, over which athletes or horses jump in a race)
çekim: çoğul gátak
köken: Borrowed from a South Slavic language, e.g. Serbo-Croatian gat, or from Slovak hať. Ultimately, from Proto-Slavic *gatь (“dike”).
