The plot centers on the two young lovers, Lydia and Jack. Lydia, who reads a lot of popular novels of the time, wants a purely romantic love affair. To court her, Jack pretends to be "Ensign Beverley", a poor officer. Lydia is enthralled with the idea of eloping with a poor soldier in spite of her guardian, Mrs. Malaprop, a moralistic widow. Mrs. Malaprop is the chief comic figure of the play, thanks to her continual misuse of words that sound like the words she intends but mean something completely different. (The term malapropism was coined in reference to the character.)(Wiki)
