I was told that sums of money take a singular verb. What about the following sentence? Which auxiliary verb should be used?

Eight million dollars have/has been appropriated for research into this strain of the virus.

You were told correctly. "Eighty million dollars" is not to be taken as eighty million separate amounts of one dollar, but as a single amount. "Has" is correct.

Purdue.edu subject-verb agreement

  1. Nouns such as civics, mathematics, dollars, measles, and news require singular verbs. The news is on at six.
    Note: The word dollars is a special case. When talking about an amount of money, it requires a singular verb, but when referring to the dollars themselves, a plural verb is required.
    Five dollars is a lot of money.
    Dollars are often used instead of rubles in Russia.

[Emphasis added]

  • But I saw "Five million dollars have been appropriated for research into the disease" in Oxford Advanced Learner's Dictionary.

  • I'd consider this to be a case where both are possible, depending on, as Jack says, whether we are considering it as a singular amount of money, or a plural number of dollars.

  • Honestly, I think the quoted advice is just wrong. Civics, mathematics, measles, and news are not plurals; they are uncountable nouns that end with the letter s: if Sue has two mathematics and her mother gives her three more mathematics, how many mathematics does she have? Any plural subject can take a singular verb when considered as a unity: four woman is too many to date at once; two meals a day is likely to leave you hungry; three examples is enough.

  • I don't think the reference said they were plural. "Four woman"? Commented Dec 16, 2020 at 17:12

An American would certainly say “Eight million dollars have been appropriated for research...” The British have a much more expansive sense of when a plural becomes a collective noun, so they might do it differently.
