This study addresses for the first time in the dedicated literature, the lexical reflexes of salt in ancient Greek, as part of an extended research project. An inventory was realized as comprehensively as possible on grammatical categories (nouns, adjectives, verbs and adverbs), derived from nominal compound ἁλ (ἅλς, ἁλὁς) in the initial and secondary position, emphasizing a majority of adjectives and a wide semantic spectrum (e.g. physical world, exploitation, food consumption and conservation, social and economic contexts, symbolic uses). This lexical variety indicates the crucial role of salt and sea in the development of Greek civilization.
