Romance linguistics was one of E. Coseriu‘s primary fields of research; all along his life Coseriu illustrated and tested his theoretical concepts using Romance languages as a touchstone. Likewise, one of Coseriu‘s early predecessors, the Spanish Renaissance philologist B. de Aldrete, came up with a number of innovative ideas concerning the historicity of language, regular changes in phonetics and transformations in morphology, divergencies among closely related languages, etymology, sociolinguistic factors (such as language contacts and cultural integration) in linguogenesis, the importance of early written texts for documenting language change, as well as other concepts, and used the example of Romance languages – the Ibero-Romance ones in particular – to support his theoretical insights. B. de Aldrete‘s treatise (1606) is also an early example of the scientific practice of citing previous research and giving references to numerous sources.
