To refer to the categorisable is to use specific categorisations of it, to express a specific model of it. For example, to refer to the perceivable as ‘the environment’ (or ‘context’ or ‘the perceivable’) is to categorise it within a larger model of meaning-making. Because of this, there is no “pre-theoretical” position that can be adopted on any subject, though some stances may be modelled as “pre-theoretical” for social-semiotic purposes.
Further, no categorisables are ineffable[1], since any categorisable can be modelled and semiosis is modelling. However, some categorisables are modelled as being ineffable for social-semiotic purposes.
