This chapter takes a look at the Lingua Franca lexicon as reflected in the Dictionnaire de la langue franque. Section 5.1 offers a bird’s-eye view of the etymological sources of the lexicon. Section 5.2 focuses on the core vocabulary of the Swadesh wordlists. Section 5.3 addresses the layered nature of the Lingua Franca lexicon, focusing on its Romance and “exotic” (Turkish and Arabic) components. Section 5.4 scrutinizes selected typological features of the Lingua Franca lexicon in relation to properties which have been identified as characteristic of pidgin lexicons, such as typical vocabulary sources and sizes; and discusses features that specifically characterize the lexicon of Lingua Franca: doublets, suppletion patterns, and selected aspects of lexical typology and idiomatic structure. It is shown throughout that the lexicon of the Dictionnaire’s Lingua Franca displays detailed, specific, and interlocking continuity with the lexical and idiomatic features of its Romance lexifiers. Section 5.5 recapitulates the main points.
