What does mated mean?
“Mated” is the past tense and past participle of “mate,” and today it is most commonly used when referring to animals paired for breeding. In this sense, it describes the act of joining sexually for reproduction or the result of that pairing: a mare may be mated with a stallion, and two dogs may have been successfully mated. The word can also be used for people to mean married or united, but that usage is less common and can sound formal or traditional. In animal contexts, “mated” often forms established phrases such as “mated pair” and “mated with.” Although “mate” itself has a wide range of meanings involving companionship, pairing, and informal address, “mated” most often emphasizes a reproductive pairing. It is therefore a useful word for discussing animal husbandry, breeding, and biological reproduction, while its application to human relationships should be used with awareness of its somewhat dated tone.

"The cows were mated with a prize-winning bull."

Where does mated come from?
“Mated” is an inflected form of the English word “mate,” which was recorded in Middle English for a companion or fellow. The word’s precise historical development is debated, but it is associated with Old French and Latin forms referring to a companion or associate. English later extended the word to mean marriage or a sexual partner, and the modern reproductive sense developed especially in relation to animal breeding.
