Most of the villagers have professions and supply certain goods. They have a different appearance that helps to identify them. Armorers will trade various iron, chainmail, and diamond armor for emeralds. You can get emeralds and meat from butchers. Cartographers trade maps and banners for emeralds and compasses. To get gemstones, visit a cleric villager. Fletchers will help you to get crafting and hunting tools. Other villager professions include farmers, fishermen, leatherworkers, librarians, shepherds, and more. Some villagers are unemployed – they look like a plain villager model without any additional details. You can find them a job by building a new job site. Another non-trading villager type is Nitwit. They wear green coats and shake heads if you attempt to trade.
