In the first four books Rabelais seldom repeats himself.

The fifth book contains from the point of view of the vocabulary really the least novelty.

On the contrary, it is full of words and expressions already met with, which is very natural in an imitation, in a copy, forced to keep to a similar tone, and to show by such reminders and likenesses that it is really by the same pen.

A very striking point is the profound difference in the use of anatomical terms.

In the other books they are most frequently used in a humorous sense, and nonsensically, with a quite other meaning than their own; in the fifth they are applied correctly.
