Etymology
The word 'streambed' is a transparent English compound, formed by combining two native Germanic nouns. 'Stream' originates from the Old English 'strēam', which referred broadly to a current or flow, not only of water but also of air or light. 'Bed' derives from Old English 'bedd', initially meaning a sleeping place or a plot of ground for plants, thus carrying the sense of a supportive foundation. The logic of the compound is straightforwardly descriptive: it names the supportive base or channel that contains the flowing water, much like a bed holds a sleeper or a garden bed holds plants. This literal combination of 'water current' and 'foundational layer' perfectly captures the physical geography of a river's course.
