apology (n.)youdaoicibaDictYouDict[apology 词源字典]
early 15c., "defense, justification," from Late Latin apologia, from Greek apologia "a speech in defense," from apologeisthai "to speak in one's defense," from apologos "an account, story," from apo- "from, off" (see apo-) + logos "speech" (see lecture (n.)).

The original English sense of "self-justification" yielded a meaning "frank expression of regret for wrong done," first recorded 1590s, but this was not the main sense until 18c. The old sense tends to emerge in Latin form apologia (first attested in English 1784), especially since J.H. Newman's "Apologia pro Vita Sua" (1864).[apology etymology, apology origin, 英语词源]
googol (n.)youdaoicibaDictYouDict
number represented by 1 followed by 100 zeroes, 1940, in "Mathematics and the Imagination," a layman's book on mathematics written by U.S. mathematicians Edward Kasner (1878-1955) and James R. Newman, the word supposedly coined a year or two before by Kasner's 9- (or 8-) year-old nephew (unnamed in the book's account of the event), when asked for a name for an enormous number. Perhaps influenced by comic strip character Barney Google. Googolplex (10 to the power of a googol) coined at the same time, in the same way, with plex.
tendential (adj.)youdaoicibaDictYouDict
1877, from Latin stem of tendency + -al (1). Related: Tendentially.
Tendenziöse is a term that has become very common in Germany to describe the Tübingen criticism, and has arisen from the lengths to which theologians of this school have shown themselves ready to go, to establish the hypothesis that the New Testament writings arose out of conflicting tendencies in the early church and efforts to bring about compromises between these factions. The word has been transferred in the translation under the form "tendential." [translator's preface to "Hermeneutics of the New Testament" by Dr. Abraham Immer, translated by Albert H. Newman, 1877]
