I think it depends on the individual and the location… My grandfather (1883 - 1950) could read, write, and speak-where-spoken 21 languages, including modern and old English, French, German, Italian, Latin, Greek, Coptic, Arabic, Hebrew, Sumerian, Sanskrit and Ancient Egyptian. (He was an Egyptologist, who attended English “Public School”, where he was taught Greek and Latin. But he never went to University, and the other languages were learned independently (he taught himself to read Egyptian Heiroglyphs at age 14).)
Even in the late 1940s my father had to pass exams in Greek and Latin to attend Cambridge University, to study physics.
