: exhibiting or relating to design or purpose especially in nature

Did you know?

Perhaps teleological was destined to serve a role in English. The word, along with its close relative teleology, comes to us by way of New Latin, from the Greek root telos, meaning "end or purpose." Both entered English in the 18th century, followed by teleologist in the 19th century. Teleology has the basic meaning of "the study of ends or purposes." A teleologist attempts to understand the purpose of something by looking at its results. A teleological philosopher might argue that we should judge whether an act is good or bad by seeing if it produces a good or bad result, and a teleological explanation of evolutionary changes claims that all such changes occur for a definite purpose.
