How to Pronounce MAN vs. MEN – American English
“One man” changes to “two men.” If we wanted to say that a car belonged to one man, we would say: “the car is the man’s.” If we wanted to say that a car belonged to two men, we would not say: “the car is the mens. ‘” This would mean that there were multiple “mens,” which isn’t possible because “men” is already plural.
