This Sunday, Pope Francis canonized Mother Teresa as a saint, joining her with 10,000 other such holy figures in the Catholic Church. That’s a lot of saints, but canonize is still a relatively rare word. So, why is this process called canonization?
To canonize is to place a deceased person in the Church’s canon of saints. The Oxford English Dictionary (OED) first cites this canonize around 1380. We can think of this canon, sometimes known as a calendar, as a kind of list; a saint’s placement on this register only takes place by official decree and according to the rules of the church. Indeed, canon means “rule” or “law,” originally of the church. This usage of canon, again as the OED dates it, is found in Old English by 890.
While influenced by French in Middle English, the Old English canon comes from the Latin canon, a “rule” or “standard,” taken from the Greek κανών (kanon, meaning the same). (Medieval Latin had canonizāre, the immediate source of canonize.) If we dig deeper, we find that both the Latin canon and Greek kanon are metaphorical in origin: Latin canna and Greek κάννα (kanna) literally mean “reed.” A reed, as we might understand it, is like a proto-measuring rod. It sets a regular length, which can be used as a model, a standard, a rule for something, hence, its application to law.
The words cane, cannon, and canyon – reeds are tubular – are all related to canon. Generic canon, that is, secular rules or standards, is evidenced by the late 1500s and early 1600s. The canon of literature, at least according to the OED’s account, is found by the 1920s, anticipated by earlier such usages of canon in the mid-1800s. The secular canon, we should note, takes a page from the religious: Since the 1380s canon has also been referring to an authoritative list of books of the Christian Bible.
Excepting its secular extensions, canon connotes Christianity. But the more ancient story of its Latin and Greek roots are anything but. Most etymologists agree that the Latin canna and Greek kanna sprouted up on Semitic shores. As the Barnhart Dictionary of Etymology explains it, canon ultimately grew out of the Babylonian-Assyrian qanū, “reed.” This, in turn, is from the Sumerian – yes, Sumerian – gin, likewise meaning “reed.” Cognates include the Hebrew qāneh and the Arabic qanāh.
As Catholics observe Mother Teresa’s new place in the canon of saints, her canonization adds to the long life of a very well-traveled metaphor indeed.
