chalk

Which Means:

A small white stick that is used to write on blackboards.

In schools, many teachers use colored markers on whiteboards, not chalk on blackboards.

This work has a silent L before the K, just like talk or walk.

Traditions, or people who practice them.

There is a folk music concert this weekend.

You can also say 'folks'; this means your parents or people in general. But the L is silent.
