Funnily the word "font" is in fact now used in digital publishing for what is more properly called "typeface". In traditional typesetting "font" refers to one specific size, weight and style of a typeface. That is, Helvetica is a typeface, Helvetica Light Oblique 12pt is a font.
I only know because a friend of mine studied design at the university.
Seems fine to me, it’s a fun piece of trivia for me that I am happy my friend told me. And at the same time, I don’t feel cheated for not having learned it myself in my education as mine was not in design :p
Also it does open up a neat avenue for designers to troll people if they are feeling mischievous.
Client: “This looks great, but could we try a different font?”
