undreamed-of
Never even conceived
Undreamed-of describes something so extraordinary or unexpected that no one could have imagined it beforehand.
The term emphasizes how far beyond normal expectations something lies: The internet brought undreamed-of access to information.
It typically modifies positive developments—opportunities, wealth, possibilities—though it can apply to anything that exceeds what was thought possible.
The hyphenated form is standard, though *undreamed of* without the hyphen appears in predicative use: Such advances were undreamed of a century ago.
