termite (n.)

1849, back-formation from plural form termites (1781), from Modern Latin termites (three syllables), plural of termes (genitive termitis), a special use of Late Latin termes "woodworm, white ant," altered (by influence of Latin terere "to rub, wear, erode") from earlier Latin tarmes. Their nest is a terminarium (1863). Earlier in English known as wood ant or white ant.
