Definition

To foster something means to encourage and help it develop over time.

To foster means to support the growth or development of something such as an idea, relationship, or skill. It often involves creating the right conditions, offering guidance, and removing obstacles. It can also mean to care for a child temporarily in your home without legally adopting them.

Examples
