position [position 词源字典]: position: [15] Position comes via Old French from Latin positiō, a noun formed from posit-, the past participial stem of Latin pōnere ‘put, place’. This was also the source of English posit [17], positive [13] (which etymologically means ‘placed down, laid down’, hence ‘emphatically asserted’), post (in the senses ‘mail’ and ‘job’), and posture [17].

And in addition it lies behind a wealth of English verbs (compose, depose, dispose [14], expose [15], impose, interpose [16], oppose, repose, suppose, transpose [14], etc) whose form underwent alteration by association with late Latin pausāre ‘stop’ (see POSE); postpone exceptionally has retained its link with pōnere.

predicament: predicament: [14] Predicament was originally a technical term in logic, denoting a ‘category of attributes which may be asserted of a thing’. It broadened out in the 16th century to ‘situation’, but it does not seem to have been until the 18th century that the specific modern sense ‘awkward situation’ became established. The word comes from late Latin praedicāmentum, a derivative of praedicāre ‘proclaim’ (source of English preach and predicate [16]). This was a compound verb formed from the prefix prae- ‘in front of’, hence ‘in public’ and dicāre ‘make known’.
=> preach, predicate
alleged (adj.): mid-15c., "quoted," past participle adjective from allege. Attested from 1610s in sense of "brought forth in court;" 1670s as "asserted but not proved."
assert (v.): c. 1600, "declare," from Latin assertus, past participle of asserere "claim, maintain, affirm" (see assertion). Related: Asserted; asserting. To assert oneself "stand up for one's rights" is recorded from 1879.
crestfallen (adj.): 1580s, past participle adjective, but the verb crestfall is recorded only from 1610s, in reference to diseased horses, and is rare. It's possible that the image behind this use of the word is not cocks, as often is asserted, but horses.
insistent (adj.): 1620s, "standing on something," from Latin insistentem (nominative insistens), present participle of insistere (see insist). Meaning "dwelling firmly on something asserted" is from 1868. Related: Insistently.
penguin (n.): 1570s, originally used of the great auk of Newfoundland (now extinct), shift in meaning to the Antarctic bird (which looks something like it, found by Drake in Magellan's Straits in 1578) is from 1580s. Of unknown origin, though often asserted to be from Welsh pen "head" (see pen-) + gwyn "white" (see Gwendolyn), but Barnhart says the proposed formation is not proper Welsh. The great auk had a large white patch between its bill and eye. The French and Breton versions of the word ultimately are from English.
predicament (n.): early 15c., "category, class; one of Aristotle's 10 categories," from Medieval Latin predicamentum, from Late Latin praedicamentum "quality, category, something predicted, that which is asserted," from Latin praedicatus, past participle of praedicare (see predicate). Praedicamentum is a loan-translation of Greek kategoria, Aristotle's word. The meaning "unpleasant situation" is first recorded 1580s.

Realtor (n.): 1916, "real estate agent," American English, coined by real estate agent Charles N. Chadbourn of Minneapolis, Minn., to distinguish the legitimate section of the business; popularized 1920s; patented as Realtor by the National Association of Real Estate Boards.
The 1916 Convention of the National Association of Real Estate Boards (NAREB) approved the adoption of the term as the official designation of an active member of the Association. In 1920 the District Court of Hennepin County, Minnesota, decided in favor of the Realtors in a case against a telephone directory publisher that had indiscriminately used the word in listings. The court asserted that the word "had never been used in any way whatsoever until so invented" and could thus be used only by those duly licensed by the National Association of Real Estate Boards. Until the Lanham Acts of 1948 changed federal patent regulations to allow protection for registered collective marks, the National Association fought and won sixteen cases on the local and state levels to protect its symbolic property.
