Interesting examples of plural forms! I came across the word "monies" (as the plural form of "money") in a contract and I found it hard to identify the word at first. Then I looked it up in the dictionary and this is what I got:

drawing account

Accounting: Name of the account (in the account books of a sole-proprietorship or partnership firm) which records all monies taken out of the business by the owner or partners.

equity method

Method of accounting used by a parent firm for monies invested in the subsidiaries. The parent firm records the investment in its balance sheet at a valuation that takes into account the profits and losses of the subsidiaries since their acquisition. Also called equity accounting. See also cost method.

Canadian usage permits "beer" as a plural; American usage, as far as I know, does not.

Linguists call the line between two such usages an "isogloss" (literally, "same language"). Just as an isobar on a weather map describes a region of equal air pressure, an isogloss describes a region where most people follow a particular usage or pronunciation. In the "beer" example, the isogloss runs right along the US-Canadian boundary.

Similarly, isoglosses separate British "lorry" and North American "truck," and Californian "fender bender" and Tennessee "car smash" ....

I suspect isoglosses also exist between social classes and generations. My generation uses "said" for "said." My students use "like":

"So Crawford is like, 'We have a quiz on Monday,' and I'm like, 'Omigod, I can't be there!"
