Five forms of the modal particle are attested in ancient Greek (ἄν, κε, κεν, κᾱ, and κ’). This article argues that ἄν is an inherited particle, and that the k-forms were the result of reanalysis of prevocalic οὐκ and εἰκ (i.e. εἰκ was reanalysed as εἰ κ’), supported by the vestiges of an old topicalising/conditional force of the IE particle *kwe (which appears elsewhere in Greek as connective τε). The attested forms in Greek grew out of *kwe in contexts where an adjacent u caused the labiovelar *kw > k (West Greek κᾱ was influenced by indefinite *kwā). The form κεν is a creation of epic diction.
