If verbs and nouns in simple word form, then generally yes. But you have to ask "Is this a sell-able product or service?" or "Who would buy this and why?". The are lots of obscure words and word forms in the dictionary that are not in common use or have little or no value to anyone. A general advantage for dictionary words, even when they don't directly represent a product or service, is that they may potentially be easier to remember and spell e.g. "go.com".
