美国法律硕士LLM全称

LL.M.是来源于拉丁语，代表法学硕士Master of Laws.
法学硕士在拉丁语中是Legum Magister。
这就涉及到语法了。
在拉丁语中，一个复数词的缩写是重复该单词单数缩写字母。
LL.M.中的LL是Legum的缩写复数。Legum是拉丁语中的lex的复数，Lex是法律之意。法学女硕士为Legum Magistra；法学学士为LL.B，即Legum of Baccalaureus；法学博士为LL.D即Legum of Doctor。

P.S:法学硕士有很多种类，LL.M.在美国是一个一年的法律速成班，美国本国学生基本上以读JD（Juris Doctor）为主，可以说LL.M.就是专门为国际学生准备的一个一年制课程，严格的说是9个月..

Good Luck buddy

LL.M. is an abbreviation of the Latin Legum Magister, which means Master of Laws. In Latin, the plural form of a word is abbreviated by repeating the letter. Hence, "LL." is short for "laws." Legum is the possessive plural form of the Latin word lex, which means "specific laws", as opposed to the more general concept embodied in the word jus, from which the word juris and the modern English word "justice" are derived.
