ologist

The suffix "ologist" is commonly attached to the end of words to denote a person who studies or is an expert in a particular field of study. This suffix is derived from the Greek word "-logia," meaning "study of" or "science of." Therefore, when "-logist" is added to a scientific discipline, it designates an individual who specializes in that area.

For instance, someone who studies geology is a geologist, and a person specializing in biology is a biologist. This linguistic pattern extends across a vast array of academic and scientific disciplines. Examples include psychologist (one who studies the mind and behavior), dermatologist (one who studies the skin), and archaeologist (one who studies human history and prehistory through the excavation of sites and the analysis of artifacts). The "-ologist" suffix signifies a dedicated pursuit of knowledge and expertise within a specific domain. It implies formal training, research, and a significant understanding of the subject matter. The term is widely recognized and understood across many languages that have borrowed from Greek or Latin roots.
