Etymology

The word inoculum comes from Latin parts in- 'in' and oculus 'eye', because gardeners once used a plant 'eye', a small bud, to graft into another plant. So an inoculum is a small thing 'put in' to start growth or protection, like a tiny sample placed in a body or a culture to begin an immune response or a new colony.
