Final answer:
Mr. Bounderby's name is a charactonym because it reflects his defining trait of being self-contained and symbolic of his self-made man persona.
Step-by-step explanation:
Mr. Bounderby's name is a charactonym because it suggests one of his defining character traits. A charactonym is a name given to a literary character that reflects some of their traits, attributes, or functions in the story. In Charles Dickens' novel 'Hard Times', Mr. Josiah Bounderby is a wealthy, self-important industrialist and his last name suggests bounds or boundaries, which reflects his character as being self-contained and self-sufficient to an exaggerated extent. It is emblematic of his self-made man persona, as he often touts himself as a man who has risen from poverty to wealth through his own efforts.
