Anagram

n. [Gr. ἀνάγραμμα, from ἀνά, back, again, and γράμμα, letter, something written, from γράφω, to write; Fr. anagramme.] A transposition of the letters of a name, by which a new word is formed. Thus Galenus becomes angelus; William Noy (attorney-general to Charles I., and a laborious man) may be turned into I moyl in law.
