lipid = lip<fat> + id<noun suffix>

- id (a noun-forming suffix in scientific terminology, often indicating a class of substances)
Etymology Origin:
The word "lipid" originates from the Greek lipos (fat), combined with the suffix -id, which is commonly used in chemistry to denote a class of compounds. The term was adopted into scientific vocabulary in the early 20th century to categorize fat-like substances. The Greek root reflects the substance's greasy, insoluble nature, while the suffix standardizes its classification alongside other biochemical terms (e.g., "protein," "carbohydrate").
