means An abundance of money, valuable possessions, or other wealth — enough to count as plenty by anyone's reckoning.

from From Old French 'richesse,' meaning wealth or magnificence, built on 'riche' (rich), which itself traces back through Germanic roots (akin to Old English 'rice,' meaning powerful or mighty) to an ancient sense of rule and dominion — a cousin of the Latin 'rex,' king. Curiously, 'riches' looks plural but began life as a singular: English speakers heard the '-esse' ending and assumed it was already a plural, so the word quietly shed its true singular form and stayed forever many.
