Affricate

Affricate (verb): This word has nothing to do with the continent of Africa or anything associated with it. To affricate means to rub against something (the root Latin word fricare is where we get the word friction).

Parvenu

Parvenu (noun): This is one of those words that barely even suggests its meaning. A parvenu is a person from a lower social class who suddenly becomes wealthy or successful but is still not accepted by other wealthy, successful people.

Today, you would refer to the parvenu as nouveau riche.
