stellar

Etymology

It is borrowed from Late Latin stēllāris (“of a star, starry”),^{[2][3][4][5][6]} from stēlla (“star”) with the adjective suffix that became -ar.^[2][3][7] The Latin noun is from *sterla,^[5][8][9] from the Indo-European root of star,^[5][4] and is related to Ancient Greek ἀστήρ (astḗr, “star”), Gothic 𐍃𐍄𐌰𐌹𐍂𐌽𐍉 (stairnō) and Old English steorra.^[8][10] The OED compares stellaire, stellare and estrellar.^[2]

Earliest recorded meaning

Relating to the stars or a star: 1656, in Thomas Blount's Glossographia,^{[2][11][6][5]} and Johnson (1755) quotes Milton for "stellar virtue".^[12]

Semantic evolution

From 1670 the adjective also meant star-shaped, chiefly of crystals, and in architecture of a vault ribbed like a star.^[2][5][12] The sense "leading, outstanding" (1883), originally and chiefly American, comes from the theatrical sense of star, a leading performer:^[2][5] Merriam-Webster records both the use for a film or stage star and the use for a chief role.^[6] Campus slang made stellar a general word of praise, "excellent, wonderful", recorded from 1986;^[13] Collins labels the sense "outstanding or immense" as informal.^[14]
