oksida.com
Oksida is the standard Indonesian and Malay word for 'oxide' — a compound of oxygen with another element — and appears in the same form in Bosnian and related South Slavic languages with the same meaning. The root oksi- traces directly to the Greek oxys, meaning sharp or acid, which is also the stem of 'oxygen' itself. A reader with any science background will feel the chemistry immediately; a reader without one still hears a clean, vowel-rich three-syllable word that opens with a hard consonant and lands softly.

Why six letters
Five letters is too short to carry a root and an ending, which is why five-letter .coms that are still available are mostly unpronounceable. Seven is where a name starts to split into two words in the reader's eye, and at eight it almost always has. Six is the length at which a coined name can hold a recognisable root, a soft ending, and still be read as a single word: the shape of most brand names people can spell after hearing once.
It is also the length with the most competition on the register. There are 434,158 live US trademarks that are six letters long, 8.9% of everything live, so a six-letter name nearly always has a neighbour one letter away. That is the normal condition of the length, not a flaw in a particular name; what matters is whether the neighbour is in your field. Each listing here says what the register holds and in which class.
What each listing shows
Where the name has been: whether a site ran on it, since when, and how many times it was archived. What it means: several of these are ordinary words in another language, which a founder in the right market recognises immediately. What sits near it on the trademark register, by class. And what already ranks for it in search, because a name nobody has typed before is a name you will have to teach people.
Common questions
Are six-letter .com domains still available to register?
Rarely for anything pronounceable. The six-letter space has 308 million possible strings, and the readable ones have largely been registered over thirty years. What remains free is mostly consonant strings; what changes hands is the pronounceable minority, which is what this page lists.
What is a six-letter .com worth?
Whatever it is worth to the business that needs it, which is why there are no listed prices here. Comparable names have sold for a few hundred dollars and for tens of thousands, depending on who wanted them. Say what you would build and what it is worth to you, and a person replies.
Is a six-letter name too short to trademark?
No. Length has nothing to do with registrability; distinctiveness does. A coined six-letter word that means nothing in English is among the strongest kinds of mark. The question is whether a similar mark already exists for similar goods, which each listing addresses.
Do you check the trademark register before listing?
Yes, against live US federal marks, and the result is on each listing. It is a signal, not a clearance, and it covers the United States only. See the resource on reading a near match for how to weigh what it shows.
