principal city of the Netherlands; the name is a reference to the dam (see dam (n.1)) built on the Amstel river. The river name is said to be from Germanic elements ama "current" and stelle "place." Prevalence of dam in Dutch place names (Rotterdam, Edam, etc.) reflects the geography of Holland. In rhyming slang, "ram" (e.g. for one who "butts in" a queue).
