What does infrahuman mean?
Infrahuman means below the level of human beings, especially in development, behavior, intelligence, or status. The term may describe an animal or artificial system whose capacities fall short of those normally associated with humans, and it can also function as a rare noun for a being considered inferior in development to human beings. Its wording is formal and uncommon, but it distinguishes being merely less than human from being cruel or heartless, which is the concern of the word inhuman. In modern philosophical and scientific discussion, infrahuman is sometimes used to explore the status of animals and artificial intelligence without making explicitly biological claims. For ordinary prose, subhuman is usually the more familiar alternative, while infrahuman offers a compact and technical expression. The word belongs to the conceptual contrast between human, superhuman, and nonhuman forms of existence.

Where does infrahuman come from?
Infrahuman was formed in English from the Latin-derived prefix infra-, meaning “below,” and human. The first element is also the source of words such as infrastructure and subterranean, while human continues the Latin word humanus, meaning “human.” The compound developed as a formal way to describe something below the human level.
