Given the question: Information: - A gelding is a castrated horse or other equine, such as a donkey or a mule. Castration, as well as the elimination of hormonally driven behavior associated with a stallion, allows a male horse to be calmer and better-behaved, making the animal quieter, gentler and potentially more suitable as an everyday working animal. As a verb, "gelding," or "to geld," refers to the castration procedure itself. - The Indo-European languages are a language family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by "Ethnologue", with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindustani (Hindi and Urdu), Portuguese, Bengali, Russian, Persian and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language natively, by far the highest of any language family. - The classical Latin alphabet, also known as the Roman alphabet, is a writing system originally used by the ancient Romans to write the Latin language. The Latin alphabet evolved from the visually similar Cumaean Greek version of the Greek alphabet, which was itself descended from the Phoenician abjad, which in turn was derived from Egyptian hieroglyphics. The Etruscans who ruled early Rome adopted the Cumaean Greek alphabet which was modified over time to become the Etruscan alphabet, which was in turn adopted and further modified by the Romans to produce the Latin alphabet. - H.O.R.S.E. is a form of poker commonly played at the high-stakes tables of casinos. It consists of rounds of play cycling among: - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets. - A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings. - The Greek alphabet has been used to write the Greek language since the late 9th century BC or early 8th century BC It was derived from the earlier Phoenician alphabet, and was the first alphabetic script to have distinct letters for vowels as well as consonants. It is the ancestor of the Latin and Cyrillic scripts. Apart from its use in writing the Greek language, in both its ancient and its modern forms, the Greek alphabet today also serves as a source of technical symbols and labels in many domains of mathematics, science and other fields. - The donkey or ass ("Equus africanus asinus") is a domesticated member of the horse family, Equidae. The wild ancestor of the donkey is the African wild ass, "E. africanus". The donkey has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries. - Neutering , from the Latin neuter ( of neither sex ) , is the removal of an animal 's reproductive organ , either all of it or a considerably large part . '' Neutering '' is often used incorrectly to refer only to male animals but the term actually applies to both sexes . The male - specific term is castrating while spaying is usually reserved for female animals . Colloquially , both terms are often referred to as fixing . In male horses , castrating is referred to as gelding . Modern veterinary practice tends to use the term '' de-sexing '' . Neutering is the most common sterilizing method in animals . In the United States , most humane societies , animal shelters and rescue groups urge pet owners to have their pets neutered to prevent the births of unwanted litters , contributing to the overpopulation of unwanted animals in the rescue system . Many states require that all adopted cats , kittens , dogs and puppies be sterilized before going to their new homes . The practice has been advocated in radio and television commercials and on various shows , most notably the game show The Price is Right , whose host , Bob Barker , would end every episode with the catchphrase '' Help control the pet population ; have your pets spayed or neutered . '' After Barker 's retirement , Drew Carey continued to sign off with his own message regarding spaying and neutering . - The MULtilingual Enhancement (MULE) is computer software which adds extra written language characters to the GNU Emacs text editor and programming environment. - A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. They may be close members of the family, such as guide dogs or other assistance dogs, or they may be animals trained to provide tractive force, such as draft horses or logging elephants. The latter types of animals are called draft animals (draught animals) or beasts of burden. Most working animals are either service animals or draft animals. They may also be used for milking or herding, jobs that require human training to encourage the animal to cooperate. Some, at the end of their working lives, may also be used for meat or other products such as leather. - A classical language is a language with a literature that is "classical". According to UC Berkeley linguist George L. Hart, "it should be ancient, it should be an independent tradition that arose mostly on its own, not as an offshoot of another tradition, and it must have a large and extremely rich body of ancient literature." - A verb, from the Latin "verbum" meaning "word", is a word (part of speech) that in syntax conveys an action ("bring", "read", "walk", "run", "learn"), an occurrence ("happen", "become"), or a state of being ("be", "exist", "stand"). In the usual description of English, the basic form, with or without the particle "to", is the infinitive. In many languages, verbs are inflected (modified in form) to encode tense, aspect, mood, and voice. A verb may also agree with the person, gender, and/or number of some of its arguments, such as its subject, or object. Verbs have tenses: present, to indicate that an action is being carried out; past, to indicate that an action has been done; future, to indicate that an action will be done. What entity does 'neutering' has the relation 'instance of' with?
The answer is:
action
