genie, genius, genuine, Ingenious, ingenuous, ingenuity, ingenuousness, disingenuous, indigenous 這幾個字非常難搞，拼法唸法意思都很容易搞錯。
首先，請讀者先把唸清楚： genius /ˈdʒiː.ni.əs/ = 天才 & genuine /ˈdʒen.ju.ɪn/ = 真的、真誠的。
第一層變形
從 genius 衍生成 ingenious = （人）靈巧的；（物品等）製作精巧的；（方法等）巧妙的。注意到沒變的部份是 geni。
從 genuine 衍生成 ingenuous = 天真的；胸無城府的。注意到不變的部份是 genu。頭尾的部份和「靈巧的」英文頭尾完全相同。
第二層變形
ingenious 變名詞後 = ingenuity = 心靈手巧；足智多謀；獨創力。這邊注意！geni 變成 genu，也就是這個地方讓人頭很大，很容易搞錯。而 ingenuous 變名詞後 = ingenuousness
其他衍生字
- disingenuous = （人或其行爲）不夠誠實的，不夠坦白的
- genie = 精靈
- indigenous = 本地的
