The origin of the term ‘lingua franca’ is unclear. According to Ostler (2010, p. 7), lingua franca “seems to be a retranslation of some Eastern-Mediterranean term for ‘language of the Franks’”. Ostler also notes (2010, p. 4) the “original ‘Lingua Franca’ was once a particular language … the common contact language of the Eastern-Mediterranean in the first half of the second millennium, the pidgin Italian in which Greeks and Turks could talk to Frenchmen and Italians”. He defines a lingua franca as a “contact language used for communication among people who do not share a mother tongue” (2010, p. 36). Seidlhofer points out that the term has Latin roots meaning something like ‘free language’. “It is thus not fanciful to think of ‘Lingua Franca’ as ‘free language’ … a means of intercultural communication not particular to countries and ethnicities, a linguistic resource that is not contained in, or constrained by traditional (and notoriously tendentious) ideas of what constitutes a ‘language’” (2011, p. 81).
