RJ,
If you've found an available English dictionary word, it likely has no - or very low - value. At least in "dot com".
The chances of finding an unregistered one dictionary word with value (.com) in this day and age is almost 0%. BUT you never know, maybe there is one or two words out there that thousands of us have missed.
There may be a lot of dictionary words available in extensions other than "dot com", but a LOT of other factors then come in to play that only time, knowledge and experience with those extensions can answer.
Good Luck!
