The Full Story

Old Englishbefore 900 CEwell-attested

From Old English 'saed' (sated, full, heavy with food, weary, tired of), from Proto-Germanic *sadaz (sated, having had enough), from PIE *seh2- (to satisfy, to satiate, to fill to capacity). The root's original meaning was fullness — not lack but excess. A sated creature is heavy, slow, and disinclined toward further activity; the Old English 'saed' described a state of biological completion, not emotional desolation.

then heavy in spirit. The same PIE root gave Latin 'satis' (enough — directly giving English 'satisfy,' 'satiate,' and 'saturate'), and 'satur' (sated, full — giving 'satire' via the 'mixed' full dish of the satura lanx), as well as Gothic *sads and Old Norse 'sadr' (full, sated). By Middle English the 'full' meaning was already retreating; by 1300 'sad' primarily meant 'firmly settled, heavy, steadfast' and by 1400 'sorrowful, downcast.' Nothing survives of the original 'sated' sense in modern English — the word has completed one of the more poignant semantic journeys in the language, from a belly full of food to a heart full of grief. Key roots: *seh₂- (Proto-Indo-European: "to satisfy, to have enough").
