A guild is an organized group of people who share the same craft, trade, or profession and work together to protect their interests and maintain standards. In medieval Europe, guilds were powerful organizations that controlled who could practice certain trades. If you wanted to become a blacksmith, baker, or goldsmith, you had to join the local guild and follow its rules.

Guilds trained new craftspeople through a system of apprenticeships. A young person would spend years learning from a master craftsperson, gradually developing the skills needed to create high-quality work. The guild made sure its members didn't compete unfairly with each other and that customers received good products at fair prices.

Today, we still use the word guild for professional organizations, though they work differently than medieval guilds. The Screen Actors Guild represents film and television actors. Writers and artists sometimes form guilds to share knowledge and support each other's work.

In modern video games, a guild is a group of players who team up regularly to accomplish goals together. These gaming guilds echo the original idea: people with shared interests working together and helping each other improve their skills.
