Why Is There Confusion over the Plural of Money?

Confusion arises because money is typically a mass noun. A mass noun is a noun without a plural form. They refer to items that can't be counted (e.g., rice, milk, chalk).

Occasionally, money can be countable. This is usually the case in a law or accounting context. The plural is moneys or monies.

Monies is more common than moneys. This is unusual because most nouns that end in –ey take a standard -s plural (e.g., monkeys, chimneys, turkeys). Moneys naturally follows that pattern.
Some critics suggest that monies encourages a pronunciation akin to the plural nouns ponies or cronies. Despite this, monies remains the more common spelling.
