Empty and Full

The words “empty” and “full” describe how much space or capacity is occupied. An empty container has nothing inside it, while a full container has reached the amount it can hold under the conditions being considered. A glass with no drink in it can be called empty; the same glass filled with water up to its rim is full.

Between these two situations, a container may be partly filled. The words are therefore often relative to the container and the situation. A large bottle can be full even though it contains more liquid than a small bottle, and a box may be full of toys without being completely filled with material.

The difference between empty and full is especially useful when talking about containers, spaces, and quantities. A container has a limited capacity, meaning there is a maximum amount it can hold without spilling or changing its shape. If some of its contents are removed, it becomes less full; if more are added, it becomes fuller.

In everyday language, “empty” does not always mean that absolutely no particles are present: a supposedly empty bottle still contains air unless it has been specially evacuated. These simple words help children compare quantities, describe everyday situations, and understand ideas such as capacity, amount, and change. They can also observe that the same object can move from empty to full gradually as something is added.
