Four … consonants [in the Czech language] are created by adding a haček, literally a “little hook,” above the letters c, r, s, and z. As a result, č is equivalent to “ch” in “cheese,” š to “sh,” and ž to “zh” as in “leisure.” The sound ř, distinctive of the Czech language, is considered virtually unpronounceable by foreigners. Something like a combination r plus ž, it occurs, to give a famous and familiar example, in the name of the composer Antonín Dvořák (usually, “Dvor-zhak”).
