This paper describes the materiality of street signs, an unappreciated and ubiquitous type of everyday written text. Drawing on social semiotics, linguistic landscapes and writing system research, it uses a categorisation of social roles associated with street signs and of the functions of street signs applied to street signs in Newcastle upon Tyne, with some other wider examples. The materials are divided into: stone and metal signs, which use capitals and archaic letters, convey permanence and quality, and are locating in function; signs handwritten or printed on paper, which also use capitals, convey temporary status and novelty and are mostly informing; painted signs, which often use lower case, have highly individual letter forms to express identity, and are usually informing; other materials ranging from glass to snow, expressing diverse ideas of permanence. The conclusion is that the meaning of street signs depends in part on the materials they are made of, particularly to convey permanence and identity.
