So every day while driving around I see many of these license plate holders that let me know where somebody went to college, as it says "Alumni College X". The point of the message is usually to convey that the driver of the car is an alumnus/na of the school, right? Or is it to serve as a source or pride for the alumni association? I have seen some plates that explicitly state "Alumni Association" - I have no issues with this. However, I have met far too many people, even from good schools (the people who flaunt this invariably went to an Ivy or Stanford, but certainly something with a brand name), who don't properly use the singular and plural versions of alumnus/alumni. What's going on here?
