inoculus

US /ɪˈnɒkjələs/

Etymology By misremembering a neuter Latin noun as being a masculine one. The same error happens with others as well (for example, with *diverticulus/diverticuli for diverticulum/diverticula); it is relevant in scientific contexts where English uses many learned borrowings from New Latin.
