avuncular（adj.）
“of or pertaining to an uncle,” 1789年，源自拉丁语 avunculus “母亲的兄弟”，是 avus 的爱称（参见 uncle）+ -ar。幽默地用于“当当铺的”（uncle 是从17世纪到19世纪的俚语，意为“当当铺的”）。
Being in genteel society, we would not, of course, hint that any one of our readers can remember so very low and humiliating a thing as the first visit to "my Uncle"—the first pawnbroker. We have been assured though, by those whose necessities have sometimes compelled them to resort, for assistance, to their avuncular relation, that the first visit—the primary pawning—can never be forgotten. [Household Words, May 15, 1852]
身处上流社会，我们当然不会暗示我们的任何读者记得“我的叔叔”——第一次当当铺的低贱和屈辱。我们已经得到保证，有些人的需要有时迫使他们寻求他们的舅舅关系的帮助，第一次拍卖——最初的典当——永远不会被遗忘。[《家庭用品》杂志，1852年5月15日]
