doryphore

Meaning

Noun

• A petty pedant, a person who complains about minor mistakes.

Origin

• A modification of doriphore, borrowed from French doryphore ("Colorado beetle") by Harold Nicolson in 1952, presumably under the influence of the various senses of pest. The French term was a translation of the New Latin genus Doryphora, itself from Ancient Greek δορυφόρος ("lance-bearing; lance-bearer").
