Household words in what play is the word used in?

"Household words" is a phrase, not a word, and it's not specifically from a play. It's an idiom meaning something very well-known and commonly used.

However, the phrase itself has its roots in a specific context:

* Charles Dickens: He used the phrase in his 1852 novel *Bleak House* to describe the popularity of his own writing. He states, "I have read somewhere that 'Every great writer is a household word.'" This connection with Dickens solidified the phrase's use.

So, while not from a play, the phrase's origin can be linked to Dickens's work and its use in the novel *Bleak House*.
