Definition: noun a circumstance especially that is due to chance : happenstance

Quotation:

“It is only happenchance that the secretary’s waiver in this case involved laws protecting the environment and historic resources,” the groups told Judge Ellen Segal Huvelle of Federal District Court in Washington. “He could equally have waived the requirements of the Fair Labor Relations Act to halt a strike, or the provisions of the Occupational Safety and Health Act in order to force workers to endure unsafe working conditions.”

I saw this in the aforementioned article and thought it looked a bit odd. “Happenstance” is a cool word, but “happenchance” is the less frequently used synonym thereby making it much cooler.
