No dictionary word of five letters or fewer is free. These are the shortest free words, up to 6 letters, most common first. Short real words that are left tend to be rare, archaic or technical, so read one aloud before you fall for it.
The words are the ENABLE word list, a public-domain English dictionary with no names, brands or abbreviations, letters a to z only, without a list of offensive words. Each word is ranked by how often it is used, from wordfreq’s English data (90,924 of the words have a frequency there; the rest are too rare and come last, A to Z). On October 29, 2026 every word was looked up at the .com registry’s own nameservers, and every word without nameservers in the registry’s registration record, since a registered name can be on hold without DNS: 805 were registered that way and are left out. A word that was registered and has since expired counts as free. Of 200 free words we priced at Name.com, 200 sold at the normal .com price (renewing at $19.99 a year there).
The list is free to reuse under CC BY-SA 4.0, the license of the frequency data it is ordered by.

For short made-up names instead of words, see short domains you can still register, or let the finder suggest names for your idea.
