stagnant

Etymology

It is borrowed from Latin stāgnantem, the present participle of stāgnō (“to be stagnant, form a pool”),^{[2][3][4][5][6]} from stāgnum (“pool, standing water”).^[7][8][9] Etymonline and Barnhart also give French stagnant as a source,^[3][4] recorded from 1611 in Cotgrave,^[2] and Barnhart thinks it was partly formed in English to go with stagnancy (1659).^[4] Partridge calls the Latin noun of obscure origin, perhaps related to Ancient Greek σταγών (stagṓn, “a drop”),^[10] and Etymonline mentions a possible root Proto-Indo-European *stag- (“to seep, drip”).^[3]

Earliest recorded meaning

Of a fluid, at rest in a vessel: 1666, in Boyle's The Origine of Formes and Qualities, a sense obsolete by 1722.^[2][11] Barnhart and Etymonline date the word to 1666 and the 1660s.^[4][3]

Semantic evolution

From 1669 it described water or air that does not flow, often with the idea that it has become foul.^[2][12] The figurative sense, dull and lacking activity, is first recorded in Johnson's Irene (1749).^[4][2] Johnson's Dictionary (1755) still gave only the physical sense, "motionless; still; not flowing".^[13] Later it was used of trade, industry and economies that do not grow or develop.^[12][9]
