Abstract: The linguistic and conceptual systems exhibit a tight relationship considering that words are access sites to conceptual structure. However, linguistic and conceptual structures seem to combine into a sort of homogeneous system which makes the distinction between them fuzzy. The article explores the possibility of positing a type of schematic linguistic content that is unique to the linguistic system. This linguistic content comes in the form of lexical concepts and linguistic parameters. These notions will shed some light on the parametric linguistic knowledge that might be encoded in and externalized via language. This in turn, could be the feature about language that differentiates it from the closely related conceptual system.
