Subject-Verb Agreement, wondering which is correct in the following?
Our years of grammar experience have / has taught us...
Assuming "have" is correct. And that phrase "of grammar experience" doesn't determine. But I'm confused now after having read that plural "years" is thought to be singular because "years" is a measurement, I believe was the argument, here:
Measurements Generally a number, fraction, or quantity of things is considered singular if considered as a mass (ten gallons is enough) and plural if considered as separate units (ten dishfuls were slowly doled out). Sums of money, time, distances, and other similar measurements are often singular (Only years of dedication earns a climber the right to stand on such a peak).
I realize there are somewhat similar questions already on your site but I can't find one that solves completely. There are many opinions but not many final words. Thanks
