leniency

Etymology

It is formed from English lenient + -ency,^[2][3] or, as Etymonline puts it, from lenient and the abstract noun suffix -cy.^[4] Lenient is from Latin lēniēns, the present participle of lēniō (“to soothe, soften”), from lēnis (“soft, mild”);^[2][5][6] the American Heritage Dictionary takes it through an obsolete French word.^[6]

Earliest recorded meaning

The quality of being lenient: 1780, in a letter of Fanny Burney.^[2][4] Merriam-Webster gives an earlier first date, 1753.^[5]

Semantic evolution

Lenient first meant softening or soothing, of medicines and the like, from 1652, and was used of people and their actions in the sense "mild, not severe" only from 1787;^[2] leniency belongs from the start to the gentler, tolerant sense.^[2] The shorter lenience followed in 1796.^[2][4] The American Heritage Dictionary groups the word with mercy and its synonyms,^[6] and its plural, leniencies, is used for lenient acts.^[6][5]
