Q: How do I sign this word?

A: The answer may be on the Internet, in a sign language dictionary.

There are several websites, where drawings, pictures, cartoons or video can help you learn the proper signs for a particular word.

Sign Language Dictionary Sites

  • ASL Browser - This site has QuickTime videos of an adult signing words from an alphabetized list developed by the Communication Technology Laboratory at Michigan State University. An updated companion site is at Signing Savvy, with more features.
