"forbid, interdict by authority," early 15c., prohibiten, from Latin prohibitus, past participle of prohibere "hold back, restrain, hinder, prevent," from pro "away, forth" (see pro-) + habere "to hold" (from PIE root *ghabh- "to give or receive"). For form, compare inhibit, exhibit. Related: Prohibited; prohibiting.
"to stuff with pads or padding, increase the amount of," 1827, from pad (n.). Of writing, "expand by insertion of extraneous matter," 1831; transferred to expense accounts, etc. by 1890.

mid-15c. in horticulture, "act or practice of grafting buds;" 1714 in pathology, "insertion of a form of a virus in order to prevent a more serious attack of it," from Latin inoculationem (nominative inoculatio) "an engrafting, budding," noun of action from past-participle stem of inoculare (see inoculate).
Later "prevent or preclude by prior action" (c. 1600) and "be aware of (something) coming at a future time" (1640s). Used in the sense of "expect, look forward to" since 1749, but anticipate has an element of "prepare for, forestall" that, etymologically, should prevent its being used as a synonym for expect. Related: Anticipated; anticipating.
