The word "nutritionist" combines the Latin root nutri- (from nutrire, meaning "to nourish") with the noun-forming suffix -tion, indicating a process or state. The suffix -ist (from Greek -istes) denotes a person who specializes in a field. Thus, "nutritionist" literally means "one who specializes in the process of nourishment." The term reflects the scientific and professional focus on dietary health, evolving from earlier Latin and Greek influences into modern English.
