Old English milde, of persons, powers, or dispositions, "possessing softness or gentleness, good-tempered, merciful," from Proto-Germanic *milthjaz- (source also of Old Norse mildr (which also contributed to the English word), Old Saxon mildi, Old Frisian milde, Middle Dutch milde, Dutch mild, Old High German milti, German milde "mild," Gothic mildiþa "kindness"), from PIE *meldh-, from root *mel- (1) "soft," which is the source also of Latin mollis "soft."
Of weather, "not rough or stormy," late 14c. Of medicine, etc., "gentle or moderate in force, operation, or effect," c. 1400; of disease from 1744. Of rule, punishment, etc., "moderate in quality or degree, of mitigated force, not hard to endure," by 1570s. It was also used in Old English as an adverb, meaning "mercifully, graciously."
Mild goes further than gentle in expressing softness of nature; it is chiefly a word of nature or character, while gentle is chiefly a word of action. [Century Dictionary]
word-forming element denoting action, quality, or state, attached to an adjective or past participle to form an abstract noun, from Old English -nes(s), from Proto-Germanic *in-assu- (cognates: Old Saxon -nissi, Middle Dutch -nisse, Dutch -nis, Old High German -nissa, German -nis, Gothic -inassus), from *-in-, originally belonging to the noun stem, + *-assu-, abstract noun suffix, probably from the same root as Latin -tudo (see -tude).
