Abstract This paper aims to single out some pathologies of current lexical semantics, which suffers from both the trauma of immanence and the opposite anxiety of rooting all knowledge in the pre-semiotic dimension, or entrusting sense-making entirely to context. To untangle these pitfalls, the dialogue with a phenomenological cognitive semiotics may prove fertile to focus on the lexicon as a type of storage and a type of memory; that is, a type of accumulated and sedimented knowledge based on the dynamical re-pertinentization of invariants. In particular, the perspective developed by Sonesson shows striking coincidences with De Mauro’s semiotic semantics, which already provides a solid foundation for rethinking the notion of lexical field drawing on an “authentic” Humboldtian and Saussurean heritage. Therefore, I will briefly review some principles of lexical structural semantics, with the aim of showing how these notions, once emancipated from the Saussurean vulgata, can not only be compatible with a cognitive phenomenological approach, but also facilitate the rehabilitation of a theoretical apparatus still valuable for both (lexical) semantics and semiotics. Although focused on lexical fields, some of the issues addressed can be extended to language and languages, as well as to other types of semiotic systems, to shed light on controversial themes such as the embodiment of signs and the autonomy of linguistics and semantics.
