block-long

The compound 'block-long' is a modern English formation, combining two native English elements to create a specific descriptive term. The first element, 'block', originally referred to a solid piece of material but evolved in urban contexts to denote a rectangular area of land bounded by streets, a sense solidified in American city planning. The second element, 'long', is a fundamental Germanic adjective describing linear extent. When combined, the literal meaning 'having the length of a city block' creates a practical, concrete measurement used primarily in journalism and urban description to convey scale in relatable, everyday terms.
