Anagram Definition
An anagram uses exactly the same letters as another word, all of them, each the same number of times.
The Rule
Two words are anagrams when they hold the same letters, each repeated the same number of times. Not one letter more, not one fewer.
LISTEN and SILENT are anagrams. Both hold E, I, L, N, S, T, and so do STONE and NOTES. A word that reuses only part of the letters is not an anagram, it is a shorter word.
Accents, Capitals and Hyphens
The comparison ignores accents and capitals. CAFE and CAFÉ give the same letter sequence, so the same page, and every spelling is listed there.
Spaces and hyphens drop out the same way, which lets you search a compound name without worrying about punctuation.
Anagram, Palindrome and Pangram
A palindrome reads the same both ways, like LEVEL or ROTATOR. It has nothing to do with an anagram, which reorders the letters of another word.
A pangram is a sentence that uses every letter of the alphabet at least once. The test is different again, since what counts is the presence of each letter, not how many times it appears.
