Did you know?

We find written evidence for diminution going back to the 14th century, including use in Geoffrey Chaucer's Middle English poetical work Troilus and Criseyde. Chaucer used "maken dyminucion" ("make diminution") in contrast to the verb "encrece" ("increase"). Diminution came to English by way of Anglo-French from Latin. Its Latin ancestor deminuere ("to diminish") is also an ancestor of the English verb diminish, which entered the language in the 15th century, and the related diminishment, a synonym of diminution that English speakers have been using since the 16th century.
