From Proto-Italic *saksom, further derivation uncertain. The American Heritage Dictionary tentiatively connects it to Proto-Indo-European *sek- (“to cut”) (compare Proto-Germanic *sahsą (“knife”)), with a semantic shift from "broken-off piece" to "rock". De Vaan rejects this due to the presence of the vowel a in the Latin word, reasoning that to obtain that vowel in that position, a laryngeal must be posited (that is, the root would have to be **sh₂k-) and that a semantic connection between "rock" and "knife" (as seen in Germanic) is difficult.
