前缀 Uni-, mono-（单一, 单独）

汉：来源于拉丁语，意为“one”，在元音字母前i脱落。
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;全体一致。在这个单词中由于单词animity前的a是元音字母，所以，前缀uni中的i脱落掉了，词anim=mind
例句：There is all but complete unanimity on this issue.关于这个问题，全体人员几乎达成了一致意见。

unicorn
n. horse-like animal with one long horn独角兽，词根corn=horn（蹄，角）
例句：They decided to name their newly acquired baseball team the "Unicorn"

例句：If Dantron Inc. and MetalTech unify their efforts,nobody will be able to compete with them.
