Origin: 1350–1400; Middle English < Latin mānsuētūdō tameness, mildness, equivalent to mānsuē-, base of mānsuēscere to become tame, mild (man(us) hand + suēscere to become accustomed) + -tūdō-tude
"tameness, gentleness, mildness," late 14c., from L. mansuetudo "tameness," from mansuetus, pp. of mansuescere "to tame," lit. "to accustom to the hand," from manus "hand" (see manual) + suescere "to accustom, habituate," from PIE *swdh-sko-, from base *s(w)e- (see idiom).
