Cannon is derived from the Old Italian word cannone, meaning "large tube", which came from Latin canna, in turn originating from the Greek κάννα (kanna), "reed",[18] and then generalised to mean any hollow tube-like object; cognate with Akkadian qanu(m)[19] and Hebrew qāneh, "tube, reed".[20][21][22] The word has been used to refer to a gun since 1326 in Italy, and 1418 in England. Both of the plural forms cannons and cannon are correct and in common usage, with one or the other having preference in different parts of the English-speaking world. Cannons is more common in North America and Australia, while cannon as plural is more common in the United Kingdom.[20][23]
What is the difference between cannon and canon?
Noun
Cannon and canon are occasionally confused by writers, but the two words have independent origins, and do not share a meaning. Cannon is most frequently found used in the sense of "a large gun," and can be traced to the Old Italian word cannone, which means "large tube." Canon, however, comes from the Greek word kanōn, meaning "rule." Although canon has a variety of meanings, it is most often found in the senses of "a rule or law of a church," "an accepted rule," or "a sanctioned or accepted group or body of related works." A loose cannon is "a dangerously uncontrollable person or thing." There are no loose canons.
