For a cognitive continuum underlying the distinction between arguments and adjuncts

The main aim of this paper is to resystematize the traditional discrete distinction between arguments and adjuncts within the cognitive continuum of subjectivity (Langacker 1990, 2007). From this perspective, the traditional discrete distinction between argument and adjuncts can be reinterpreted in a continuistic way (Mereu 2020). To achieve this, we will qualitatively analyse the behaviour of an Italian adverbial preposition of limitation, riguardo (a)NP ‘regarding NP’, showing how the different roles it assumes with respect to the argument structure can be traced back to a different subjective or objective construction of the relation it establishes.
