Word Origin & Etymology
From Late Middle English, derived from the Latin 'inoculatio', meaning 'an engrafting of buds' (from 'in-' meaning 'into' + 'oculus' meaning 'eye' or 'bud'). Originally a horticultural term for grafting a bud from one plant into another, it was adopted in the early 18th century for the medical practice of introducing smallpox matter into the skin.
