Sem"i- (?). [L. semi; akin to Gr. &?;&?;&?;, Skr. sāmi-, AS. sām-, 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.
&fist; 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.
