Did You Know?
If you think you see a connection between "inoculate" and "ocular" ("of or relating to the eye"), you are not mistaken - both words look back to "oculus," the Latin word for "eye." But what does the eye have to do with inoculation? Our answer lies in the original use in English of "inoculate" in Middle English: "to insert a bud in a plant." Latin oculus was sometimes applied to things that were seen to resemble eyes, and one such thing was the bud of a plant. "Inoculate" was later applied to other forms of engrafting or implanting, including the introduction of vaccines as a preventative against disease.
Origin of inoculate
Middle English, to insert a bud in a plant, from Latin inoculatus, past participle of inoculare, from in- + oculus eye, bud — more at eye
First Known Use: 1721

History for inoculate
Similar to the way that we use “eye” for the undeveloped bud on a potato, the Romans used the Latin word oculus, “eye,” to mean “bud of a plant.” Having learned that the oculus or bud from one plant can be grafted onto another, the Romans derived the verb inoculare from oculus to refer to the process of grafting. English borrowed this verb as inoculate with the same meaning. Introducing a small amount of material to make a person immune to a disease is like implanting a bud, so the verb inoculate was also used for this procedure.
