A mule is an animal that is the offspring of a male donkey and a female horse, known for being strong and sure-footed. It is usually sterile and cannot have babies of its own.
From Old English *mūl*, from Latin *mulus* “mule,” of uncertain earlier origin. Mules have been used as work animals for thousands of years in many cultures.
Mules are biological hybrids: they combine a horse’s size with a donkey’s toughness, which makes them excellent for difficult terrain. Because horse and donkey chromosomes don’t match perfectly, most mules can’t reproduce—each one has to be newly bred. They’re like custom-built machines rather than models that can copy themselves.
In some languages and dialects, 'mule' and related metaphors have been used to describe women as burden-bearers or stubborn, dehumanizing them and associating them with labor without agency. The term has also appeared in racist and sexist imagery comparing women of color to pack animals.
Avoid using 'mule' metaphorically for people, especially women or marginalized groups; describe specific behaviors or conditions instead of animal comparisons.

Women—especially women of color—have historically carried disproportionate physical and emotional labor; using more respectful language helps recognize that labor as human work rather than animal-like burden.
