The definition for this is very simple, dictionary domain names are names that are generated from the dictionary, for example walk.com, speak.com etc, dictionary domain names are very popular because they are short and easy to remember, there had been many dictionary domain names that have been sold for hundreds of millions of dollars kike Sex.com and others. If you go try to find one at a .com domain registration site, you’ll find it very hard to find one available.

Most of this domain names are very hard to find (I would say almost impossible), the only chance that you have of getting one of this domains is by registering another version instead of the .com for example .info.

Now in my opinion nothing can guarantee traffic, I would suggest that you find a domain that fits your business, do not go crazy buying dictionary domain names just because of nothing, the reality is that the non .com versions will not be sold for more than the registration cost, instead build your brand, your traffic and your website can be of more value than just sing.info.
