“…Interestingly, the sets of meanings contributed by the interrogative pronouns in these (not very closely related) languages do not appear to differ arbitrarily but instead intersect in several key ways. Firstly, in all three of these languages the interrogative pronoun can be used nonargumentally to mean 'why' or 'how' in questions, as in examples (10) Such non-argumental uses of interrogative pronouns can also be found in Dutch, some varieties of Norwegian (Vangsnes 2008), and the early Celtic languages (Lewis & Pedersen 1937: 226-9 (Munaro & Obenauer 1999: 211) Dutch also permits exclamatives using the interrogative pronoun wat, as in (20) , cannot be ruled out, as there are many cases of such homophony throughout attested human languages: indeed, it seems plausible that this is the case with the Old English adjective hwaet 'quick, active, vigorous, stout, bold, brave', which is generally agreed not to be related to the interrogative pronoun hwaet but to the verb hwettan 'to whet' (see, e.g., Bosworth & Toller 1898, s.v. hwaet, 2).…”
