Anagram solver · ENABLE1, 172,820 words
Every word that uses all your letters — and every pair that splits them
An anagram uses the whole rack: every letter you typed, as many times as you typed it, and nothing else. This page looks your letters up as one word, tries every way of dealing them into two words, and prints the size of both searches.
Up to 15 letters, all of which get used. No ? blanks here — the unscrambler is the page that takes those.
The word index is not loaded yet. It ships as 14 plain-text shards, one per word length; a single word pulls one, a split pulls the short ones, and your rack's figure appears here after a sieve.
What is measured, how it is kept, and what it cannot tell you
What is measured. Two things, both about the whole rack. Which entries of a named word list use exactly the letters you supplied — no letter more or fewer — and which pairs of entries use those same letters between them. There is no scoring model and no opinion about which answer is the good one; a word is in the list or it is not. The strip counts both answers and, beside them, the deals the split search enumerated — usually fewer than the pairs found, because one surviving deal often yields several word pairs — every word of one half against every word of the other.
How it is kept. The list ships as a file, wordlist/enable1.txt, precomputed at build time into an anagram-key index: each word's letters sorted, used as the key to every word that shares them. Your rack sorted is therefore a key, so one word is one lookup — the letters of SPARE sort to aeprs, which maps straight to the 12 words in ENABLE1 that share it. A two-word split is that same lookup twice, once per half, over every distinct way the rack deals into two hands, and a pair survives only when both halves are real words.
What it cannot tell you. Whether a word is allowed in your game, which depends on a word list this site does not use and cannot ship. Anything about words outside ENABLE1: proper nouns, hyphenations, and the 4,272 entries of 16 letters or more, which are in the shipped file but outside the index. And any answer of three words or more — the search here is one word or two, and the two-word half stops at a 12-letter rack.
