Hi notmike, thank you for the suggestion, but JapanDict relies on the JMDict project for its translations, and we do not have direct control over adding new words to the database.
The JMDict project is a collaborative effort involving contributions from a community of experts in the Japanese language. If you believe that a word should be added to the JMDict project, we encourage you to reach out to the project administrators or contribute to the project yourself. By participating in the JMDict project, you can help expand the database and ensure that accurate and comprehensive translations are available to a wider audience.
As this is a recurrent question, I have added this answer to the FAQ for future reference.
