A more thorough explanation:

Definition: Suitable (adjective) means that something is fit and appropriate for its intended purpose.

Examples:

• A winter coat is suitable for cold weather.
• A hammer is suitable for driving nails into wood.
• A bicycle is suitable for transportation in a city.

The examples illustrate that something is suitable when it is the right tool or item for a specific task or situation. A winter coat is suitable for cold weather because it is designed to keep a person warm in low temperatures. A hammer is suitable for driving nails into wood because it has a heavy head and a sturdy handle that can withstand the force needed to drive a nail. A bicycle is suitable for transportation in a city because it is lightweight, easy to maneuver, and can navigate through traffic and narrow streets.
