anagram

The word "anagram" is a direct borrowing from the French anagramme, which itself originates from the Greek anagrammatismos. This Greek term is a compound of the prefix ana-, meaning "again" or "back," and the root gramma, meaning "letter" or "writing." The literal sense of "writing again" or "rearranging letters" has remained remarkably consistent from its ancient origins to its modern usage. It entered English in the late 16th century, retaining the core concept of a word game or puzzle based on the transposition of alphabetic characters.

Structure: ana (again, back) + gram (letter, writing) - ana: A prefix of Greek origin meaning "again," "back," or "up." - gram: A root of Greek origin (from gramma) meaning "letter," "something written," or "a small weight."
