<i>Osborn's "Brainstorming" methodology had 2 main tenants</i><p>1. It should be <i>tenets</i>. A <i>tenant</i> is "a person who occupies land or property rented from a landlord". A <i>tenet</i> is a "principle, opinion, or dogma maintained as true by a person, sect, school; a thing held to be true"[0]. I've seen this mistake a couple of times before on programmer blogs.<p>2. I think he means <i>method</i>. It seems <i>methodology</i> is starting to take over from <i>method</i> in a lot of areas, maybe because it's longer and sounds more impressive and scientific. No-one wants to talk about their <i>method</i> when they can talk about their <i>methodology</i>. But in scientific papers, the <i>methodology</i> is the part where they explain the reasons why they're using the methods they're using. The two words mean two different things.[1] Let's keep it that way!<p>[0] The Online Etymology Dictionary goes on: early 15c., from Latin tenet <i>he holds</i>, third person singular present indicative of tenere <i>to hold, grasp, keep, have possession, maintain,</i> also <i>reach, gain, acquire, obtain; hold back, repress, restrain;</i> figuratively <i>hold in mind, take in, understand</i> <a href="https://www.etymonline.com/word/tenet" rel="nofollow">https://www.etymonline.com/word/tenet</a><p>Incidentally, I didn't realize until I started learning Spanish that "ten" or "tain" in English words means <i>to have</i>. Spanish inherited <i>tenere</i> as <i>tener</i>, to have, and adds prefixes to make a lot of other verbs, e.g. <i>abstener, contener, detener, mantener, obtener, retener, sostener</i>, all of which mean something like what they do in English - <i>to abstain, contain, detain, maintain, obtain, retain, sustain</i> - various forms of 'having' (or not having). "Ten" is in words like <i>tenacious</i> - from Latin <i>tenax</i>, holding fast, clinging, and <i>tenable</i> - capable of being held/maintained.<p>[1] "Etymologically, methodology refers to the study of methods. Thus the use of <i>methodology</i> as a synonym for methods (or other simple terms such as <i>means, technique,</i> or <i>procedure</i>) is proscribed as both inaccurate and pretentious."
