Meanings

Adjective

  1. made liquid by heat

Beyond the definition

Imagine the heart of a volcano: that glowing, flowing rock isn't just hot, it's molten. This word describes something that has been heated so much that it becomes liquid. It is not usually used for everyday things like an ice cube or butter. Instead, it often refers to things like rock, metal, or glass. You might see molten gold being poured into a mold, or read about molten lava moving down the side of a volcano. Think of something fiery, flowing, and extremely hot.
