the compound adjective "steel-and-glass" is a modern english formation that directly names its constituent materials. it emerged in the mid-20th century as a descriptive term for the international style of architecture, which prominently featured structural steel frames and large panes of glass. the term's logic is purely denotative, combining the names of the two primary materials to evoke the aesthetic and structural qualities of modernist and postmodernist buildings. its meaning has extended metaphorically to describe environments or designs perceived as cold, impersonal, or starkly modern, drawing a direct link from the literal materials to the abstract impression they create.

Structure: steel (material) + and (conjunction) + glass (material) 'steel' originates from old english 'stēle', related to proto-germanic 'stahliją', and denotes a hard, strong alloy of iron and carbon. 'and' is from old english 'and, ond', a conjunction used to connect words or clauses. 'glass' comes from old english 'glæs', from proto-germanic 'glasą', referring to a hard, brittle, transparent substance.
