No.
It's a common mistake to assume that just because a domain is "in the dictionary" that it magically has value.
There are over a million words in the largest dictionaries, but only a tiny fraction of those have any commercial application or would be familiar to the average reader.
For example, "flocculate" is a real dictionary word but it has absolutely ZERO commercial applicability so it's impossible to think of any reason why a buyer might step forward to buy it. Dictionary: YES. Value: NO.
The opposite is true though - if the word isn't in the dictionary, then it will most likely have little or no value.
What you're looking for is a combination of factors: a generic word or expression that's in the dictionary (i.e. correct spelling) AND which has clear commercial applications to an audience willing and able to pay for it, and which will benefit from owning that domain.
