Webster's Dictionary (GCIDE)

Semi- \Sem"i-\ [L. semi; akin to Gr. ???, Skr. s[=a]mi-, AS. s[=a]m-, and prob. to E. same, from the division into two parts of the same size. Cf. Hemi-, Sandelend.] A prefix signifying half, and sometimes partly or imperfectly; as, semiannual, half yearly; semitransparent, imperfectly transparent. [1913 Webster]

Note: The prefix semi is joined to another word either with the hyphen or without it. In this book the hyphen is omitted except before a capital letter; as, semiacid, semiaquatic, semi-Arian, semiaxis, semicalcareous. [1913 Webster]
