The wor conjuration (from Latin 'conjure', 'conjurare', to swear together) can be interpreted in several different ways: as an invocation or evocation (the latter in the sense of binding by a vow); as an exorcism; or as an act of illusionism. The word is often used synonymously with "invocation", although the two are not synonyms. One who performs conjurations is called a conjurer or conjuror.
