If you are seeing an error message that says something went wrong, please make sure your browser is not running an ad-blocker. We have had reports of the following features not working when an ad-blocker is enabled: log-in, neurons, bookmarks, audio pronunciation, citation, and others.

We offer The Free Dictionary as a free service to all users; alternatively, we also offer an ad-free subscription to The Free Dictionary (https://secure.thefreedictionary.com/premium/subscribe).

We have to pay our bills. Without the revenue from ads or subscriptions, The Free Dictionary and most other websites in the world would not be able to exist. Please consider this before installing software that blocks ads.
