In Czech, as in many other languages, a standard double negative is used in negative pronoun or negative conjunction phrases, the verb being also denied (“nikdo nep`i`el” – “no one came,” literally “no one came.” But this doubleness is also transmitted in forms where the verbal copula is released and where the negation is linked to the nominal form, and such a sentence can be ambiguous: “nikdo nezranén” (“healthy person” can mean both “healthy person” and “all healthy”. Similarly, “nep`tomen nikdo” or “pl-novany byly t`i`koly, nesplnén édn” (“three tasks were planned, none not accomplished”).  The phrase “véichni tam nebyli” (“not all were there”) does not mean “all absent,” but “they were not all” (at least “at least one of them absent”).
