With this, Chaucer avoids targeting any specific audience or social class of readers, focusing instead on the characters of the story and writing their tales with a skill proportional to their social status and learning. However, even the lowest characters, such as the Miller, show surprising rhetorical ability, although their subject matter is more lowbrow. Vocabulary also plays an important part, as those of the higher classes refer to a woman as a "lady", while the lower classes use the word "wenche", with no exceptions. At times the same word will mean entirely different things between classes. The word "pitee", for example, is a noble concept to the upper classes, while in the "Merchant's Tale" it refers to sexual intercourse. Again, however, tales such as the "Nun's Priest's Tale" show surprising skill with words among the lower classes of the group, while the "Knight's Tale" is at times extremely simple.
