Check if any two words are anagrams instantly. Enter any word and see all its valid anagrams. LISTEN=SILENT. 270,000+ word database. Free.
An anagram checker verifies whether two words or phrases are anagrams of each other — meaning they use exactly the same letters the same number of times. LISTEN and SILENT are anagrams: both use L, I, S, T, E, N exactly once. DORMITORY and DIRTY ROOM are anagrams: both use D,I,R,T,O,R,Y,M,O (ignoring the space). A true anagram uses every letter of the original exactly once — no additions, no omissions.
Our checker works by entering any word in Exact mode and seeing all valid anagrams in the results. If the word you want to verify appears in the results, the two words are confirmed anagrams. For phrase anagrams, enter all letters combined (without spaces).
Enter any word and switch to Exact mode. The algorithm finds all words using every one of your input letters exactly once. If your comparison word appears in the results, the two words are anagrams. The algorithm converts both sets of letters to sorted frequency maps and compares them — if the maps match exactly, the words are anagrams. This comparison is mathematically definitive: there is no ambiguity.
For two words of different lengths, they cannot be anagrams (different letter counts mean different frequency maps). Our Exact mode automatically enforces this — only words of equal length to your input can appear in results.
