I watched the BBC adaptation of Charles Dickens' Little Dorrit some weeks ago, and have happily remembered a question I had forgotten from it just now. In this dialogue, Mr. Clennam, a dashing and rich gentleman, asks Frederick Dorrit — whose brother is the principal character William Dorrit, and whose lamentable tale of being locked up in Marshalsea Prison for his debts forms the basis of the entire story — about his fortunes. As Frederick Dorrit was once guarantor to his brother's debts, his fortunes have been laid very low, and he recalls the story of his past life (paraphrasing):
Things were not always the way they are now. I was once a man of leisure. I ran a boarding school for young girls...
My question is: What exactly does it mean to be a "man of leisure"? Mr. Frederick Dorrit doesn't sound to me particularly upper-class, from his job description as a proprietor, yet he applies a very gentlemanly sounding appellation to himself. I'm thinking maybe the phrase has a more nuanced meaning than merely "free from work." Can anyone help me figure that meaning, with it associated connotations, out?
