Replacement Finder aka Algebraic Search

This page finds words that, when one string of letters is replaced with another string, are also words we know about. Wild-card characters like ? and * are not supported here.

To find words that work when specified letters are removed, leave the second text box blank.

Replacements that transform the start or end of the original word are often less interesting. Ignore those results by selecting inner-word replacements only below.
