Mmm... Interesting. I guess you could argue against your opponent trying to make a case for the etymology of 'obsolete'. This from Etymology Online: obsolete. 1570s, from L. obsoletus "grown old, worn out," pp. of obsolescere "fall into disuse," probably from ob "away" (see ob-) + solere "to be used to, be accustomed" (see insolent). This can be qualified with the Online Latin Dictionary: obsŏlētus , a, um, P. a., v. obsolesco I. fin. obsŏlesco , lēvi, lētum, 3, I. v. inch. n. [obs-olesco], to wear out, to grow old, decay, fall into disuse, lose value, become obsolete (class.; “syn. exolesco): his (verbis) oportet, si possis, non uti: sic enim obsolescent,” Varr. L. L. 9, § 16 Müll.: “haec ne obsolescerent, renovabam, cum licebat, legendo,” Cic. Ac. 1, 3, 11: “obsolevit jam oratio,” id. Imp. Pomp. 17, 52: “vectigal, quod in bello non obsolescat,” id. Agr. 1, 7, 21: “laus,” Tac. A. 4, 26: “enituit aliquis in bello, sed obsolevit in pace,” Plin. Pan. 4, 5.—Hence, obsŏlē tus , a, um, P. a. A. Lit., old, worn out, thrown off: “erat veste obsoletā,” Liv. 27, 34: “ vestitus,” Nep. Ages. 8, 2: “amiculum,” Curt. 6, 9, 25: “vestitu obsoletiore, Cig. Agr. 2, 5, 13: homo obsoletus,” in a worn-out dress, id. Pis. 36, 89: “tectum,” old, ruinous, Hor. C. 2, 10, 6: “verba,” obsolete, Cic. de Or. 3, 37, 150: “obsoleta et vulgaria,” id. Quint. 18, 56.— B. Transf., common, ordinary, poor, mean, low: “crimina,” Cic. Verr. 2, 5, 44, § 177: “gaudia,” Liv. 30, 42.—Comp.: “obsoletior oratio,” a too ordinary, too negligent style, Cic. de Or. 3, 9, 33: “honores,” of little worth, Nep. Milt. 6, 2: “color,” Col. 4, 30: “o nec paternis obsoleta sordibus,” Hor. Epod. 17, 46: “dextra obsoleta sanguine,” defiled, Sen. Agam. 977. —Hence, adv.: obsŏlētē , in an old or worn-out style, poorly, meanly: “ paulo tamen obsoletius vestitus,” Cic. Verr. 2, 1, 58, § 152. Not sure why the OED online changed 'practiced' to 'produced'. The etymology suggests that it is indeed a matter of 'practice' more than 'production' (note the cognate 'solere', and 'insolent'). Incidentally, so seems your opponent, the Helsinki person ('insolent'). Good luck and report if you win! Cheers, Speranza ---- In a message dated 12/1/2011 1:02:40 A.M.

I referred to my 1971 copy of the OED which says, “that which is no longer practiced or used,” and argued that since all the DSLRs produced since the E-1 in 2003 are still in use and performing as they were designed to perform and taking photos as good as any dslr still in production, they are not obsolete. He then declared my copy of the OED obsolete. Without getting into the whole argument, I’d like to hear your theory on why the Online OED would be different from my 1971 edition on this definition? Why would “practiced” be replaced by “produced”?" ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
