Minecraft wiki entry for Villager, associated text: A cleric villager and cleric zombie villager spawn locked up in the basements of igloos (if the basement generates) under the carpet of the floor. In Bedrock Edition, the villager and zombie villager inside igloo basements have random professions instead of always being clerics. The cleric villager can also turn into a leatherworker villager since the cauldron in the basement is closer to the villager.
