The title of Oscar Wilde's most successful play. The Importance of Being Earnest features a salient pun in the form of the word "Earnest<span>",
Earnest means </span><span>"<span>honest", and "truthful"
</span></span>At the very beginning of the play, we learn that Jack has created a convenient younger brother named Ernest. We don't know why he comes up with that particular name, but we’re guessing Jack had a laugh or two over it. Jack, Ernest,<span> fools his lady friends, all of whom have an obsession with the name "Ernest." Both Gwendolen and Cecily are in love with that name, based on an assumption that boys named Ernest will be as honest as the name suggests.
