Definitions

1. A type of star that is significantly larger and more luminous than a giant star, often found at the end of its life cycle
2. An astronomical classification for exceptionally massive stars that exhibit bright luminosity and expansive size compared to standard stars
3. Referring to a category of stars that surpass ordinary giants in both diameter and brightness, frequently resulting from stellar evolution processes

Etymology: Astronomers needed a word for stars bigger than giants, and they built it by bolting "super-" onto "giant," a coinage that tells you the term is a modern technical label rather than an old folk word. The giant half of the story runs back to ancient Greek "Gígas," the name of the mythical earth-born warriors, which passed through Latin "gigās" and Old French "gaiant" before arriving in English as "geaunt" in Middle English and then "giant." Those Greek giants were the children of Earth who fought the gods, so the word's deep sense was of huge, mighty beings. "Super-" comes from Latin "super," meaning "above" or "over," which shares its Proto-Italic ancestry with the Latin "super" that gives English words like "superior." Put together, "supergiant" literally means something like "above giant," and the term describes stars whose great size and brilliance place them beyond the ordinary giant class. Stars of this kind usually form at the late stages of stellar evolution, when they swell and shine far more intensely than the Sun will ever manage.
