fatuity (n.)

"愚蠢的，傻的"，来自拉丁语 fatuus "愚蠢的，无味的，傻的"，其起源不确定。巴克（Buck）认为最初是指头部受到打击。但德·范（de Vaan）表示，它来自原始意大利语 *fatowo- "关于言语"，源自 PIE 词根 *bha-（2）"说话，讲述，说"。

[I]f we connect the fact that Fatuus is said to be an alternative name for Faunus, and that he predicted the future, and that this god is attested on an Etruscan mirror as Fatuvs in a clear oracular function (Weiss 2007b), we may venture a derivation from for 'to say' (Untermann 2000). The name of the god would then have come to be used pejoratively as 'silly'. [de Vaan]

如果我们将 Fatuus 被称为 Faunus 的替代名称与他预测未来的事实联系起来，并且这个神在一面明显的神谕功能的伊特鲁里亚镜子上被证明是 Fatuvs（Weiss 2007b），我们可以冒险从 for “说”（Untermann 2000）中推导出一个词源。然后这个神的名字就被用来表示“愚蠢”的含义。[de Vaan]
