At least in the case of Hesiod's use, see Jenny Strauss Clay, Hesiod's Cosmos, Cambridge, Cambridge University Press, 2003, p.135., ISBN0-521-82392-7. Clay lists a number of researchers who have advanced some variant of the association between Hecate's name and will (e.g. Walcot (1958), Neitzel (1975), Derossi (1975)). The researcher is led to identify "the name and function of Hecate as the one 'by whose will' prayers are accomplished and fulfilled." This interpretation also appears in Liddell-Scott, A Greek English Lexicon, in the entry for Hecate, which is glossed as "lit. 'she who works her will'"
