 Work on category distinctions is also relevant to debates in linguistics and philosophy of language about what, exactly, a category mistake is, and why category mistakes are infelicitous. Analyzing category mistakes and why they are infelicitous (as Magidor 2019 makes clear) has further relevance for linguistic theories of syntax, semantics, pragmatics, and of metaphorical and fictional discourse. Magidor (2013, 2019) surveys past answers to the question of what makes a category mistake infelicitous, including: that they are syntactically ill-formed, that they are meaningless, that they are meaningful but lacking in truth-value, and that they are (despite being well formed, meaningful and having truth-value) pragmatically inappropriate. Magidor argues against the first three options, and defends instead a presuppositional account of why sentences that seem to contain category mistakes are infelicitous. Roughly, on her view, a sentence like ‘Two is green’ triggers the presupposition that two is colored – a presupposition that is difficult to accommodate (2013, 132). Thus, on her analysis, the sentence is infelicitous, but still has a truth-value (it is false).
