Welcome to, a free and open-source website designed to facilitate meanderings through the Moby Thesaurus, the largest thesaurus in the English language.

The Moby Thesaurus is a weird and wonderful reference full of unusual and illuminating word relationships. It was compiled by Grady Ward, a software engineer, lexicographer, and Internet activist.

This website was built by Zeke Sikelianos, a designer who can't stop making language tools like wordnerd, wordnik, ord, and outcasts.
