WordCmp.com is a easy-to-use tool that shows the similarities and differences between any two words, even ones that seem diametrically opposed. Put them side by side, compare their roots, and get down to the nitty gritty of what they really are. Just type in your first word (such as "cat") and then enter your second word (such as "dog"). Find out how two words are truly similar in more ways than one!

WordCmp.com is powered by WordRel.com's huge graph of words’ relations and uses it to compare the words you typed in, highlighting where they share commonalities and which parts are different.
