 Someone uttering a sentence of the form “\(S_1\) or…or \(S_n\)” generally conveys that (i) any of the \(S_1,\dots, S_n\) may be true (genuineness) and (ii) that between them, the \(S_1,\dots, S_n\) covers all the relevant possibilities (exhaustivity). While on a standard truth-functional analysis only (ii) is part of the meaning of or, Zimmermann identifies (i) as the essential contribution of linguistic disjunction with exhaustivity being conveyed by intonation or other devices, for example either … or. Evidence for this division of labor comes from the cases of so-called “open” disjunctions, i.e., disjunction with a terminal rise. In the following examples \(\uparrow\) and \(\downarrow\) indicate rising and falling pitch contours respectively.
