In the lessons

In everyday life and water safety: inflatable toys can blow away in wind or float out to sea — use them only in shallow water near an adult; armbands help but are not life jackets. In science: air pressure inside keeps an inflatable firm. Phrases: «inflatable boat», «inflatable castle», «inflatable mattress».

Examples

• We played on an inflatable castle at the party. tree →

Note

From the verb «inflate» (fill with air): inflate → inflatable (drop e). Opposite action: deflate. An inflatable is not a safety device; real life jackets are needed for boating.
