What is a donkey and mare's foal called? The RAE explains

The Real Academia Española (RAE) clarifies that the term 'mula' specifically refers to the offspring of a male donkey and a female horse. This hybrid, known for its strength and resilience, has been valued for centuries in agricultural and transport roles.

While the term 'mula' is common, its precise definition is often misunderstood. The RAE emphasizes that it exclusively denotes the offspring of a male donkey and a female horse. Hybrids, resulting from the reproduction between different species like horses and donkeys, share a common ancestor but possess genetic differences that usually render them infertile.

The mule's historical significance lies in its physical capabilities, enabling it to navigate difficult terrain and carry heavy loads. These traits made it an indispensable animal in rural activities.

Interestingly, the inverse cross, between a female donkey and a male horse, produces a 'burdégano' or hinny. This hybrid is less common and generally smaller, with specialists noting it historically saw less use due to lower physical endurance and greater training difficulty.
