It is a time when class should speak with class very frankly.

The class of 2011 represents 60 countries and speaks 59 different languages.

Lower classes may not speak to a higher class unless spoken to, and can only reply in a short answer.

The last few days have seen a neglected class speak rather loudly on its own behalf.

On the sidewalks, class speaks through clothes.

"The two classes do not speak the same language, and the ideas of the educated elite do not filter down."

Until the 20th century, only the upper classes and people in cities spoke the literary language.

The new middle class spoke explicitly of "civilizing" the dog so it might better reflect its master.

A class is, broadly speaking, an important set.

This year there were 73 classes with adults from more than 70 countries, speaking 40 different languages.
