前綴 Uni-, mono-（單一, 單獨）

漢：來源于拉丁語，意為“one”，在元音字母前i脫落。
英：
mono-
word-forming element meaning "one, alone; containing one (atom, etc.)," from Gk. mono-, comb. form of monos "single, alone," from PIE root *men- "small, isolated" (cf. Gk. manos "rare, sparse," Armenian manr "thin, slender, small," and perhaps English minnow).
uni-
word-forming element meaning "having one only," from L. uni-, comb. form of unus (see one).
unanimity
n.complete agreement or unity;全體一致。在這個單詞中由于單詞animity前的a是元音字母，所以，前綴uni中的i脫落掉了，詞anim=mind

unicorn
