Did you know?

We find "diminution" in print for the first time in Geoffrey Chaucer's poetical work "Troilus and Criseyde." Chaucer used "make diminution" in contrast to the verb "increase" (he could have used the verb "decrease," but he needed to create a weak rhyme with "discretion"). "Diminution" came to English by way of Anglo-French from Latin. Its Latin ancestor deminuere ("to diminish") is also an ancestor of "diminishment," a synonym of "diminution" that English speakers have been using since the 16th century.
