AN′TI-

[Gr., αντι, against.] In composition , before, against, contrary to, corrective of, ., more especially representing antagonism or opposition; whilst the Latin ante- is generally used in the sense of before, having reference to precedence either of place or time. Anti- is a common prefix in English words derived from the Greek and Latin, especially those connected with pharmacology and medicine, the final i being either dropped or retained (but generally the first) before a, e, and h; as in antacid, antibilious, anti-emetic, anthelmintic, anti-corbutic, antiseptic, ., whether used as adjectives or substantives. These compounds, which are very numerous, are in general self-explanatory.
