A mitten is a form of glove that does not have separate divisions for all fingers. They usually have a separate section for the thumb. They may have been sewn from leather or fabric, naalbinded or [knitting|knitted]], depending on the time or place.
Split mittens are a type of three-fingered glove which appears to have been worn in argicultural contexts during the middle ages. They had a partition for the thumb, and a further two partitions to hold two fingers each.
