You might be familiar with the Greek word homos, which means “same.” It is from this word that we get words like homonym, homogeneous, and homophone, all of which have to do with sameness or similarity. What does this have to do with anomaly? Although it’s not obvious, homos is a part of the etymology of anomaly, too. Anomaly is a descendant—by way of Latin and Middle French—of the Greek word anṓmalos, which means “uneven” or “irregular.” Anṓmalos comes from the prefix a- (meaning “not”) and the word homalόs (meaning “even”)—and homalόs comes from homos.
