belief (n.)youdaoicibaDictYouDict
late 12c., bileave, replacing Old English geleafa "belief, faith," from West Germanic *ga-laubon "to hold dear, esteem, trust" (cognates: Old Saxon gilobo, Middle Dutch gelove, Old High German giloubo, German Glaube), from *galaub- "dear, esteemed," from intensive prefix *ga- + *leubh- "to care, desire, like, love" (see love (v.)). The prefix was altered on analogy of the verb believe. The distinction of the final consonant from that of believe developed 15c.
"The be-, which is not a natural prefix of nouns, was prefixed on the analogy of the vb. (where it is naturally an intensive) .... [OED]
Belief used to mean "trust in God," while faith meant "loyalty to a person based on promise or duty" (a sense preserved in keep one's faith, in good (or bad) faith and in common usage of faithful, faithless, which contain no notion of divinity). But faith, as cognate of Latin fides, took on the religious sense beginning in 14c. translations, and belief had by 16c. become limited to "mental acceptance of something as true," from the religious use in the sense of "things held to be true as a matter of religious doctrine" (a sense attested from early 13c.).

Spelling beleeve is common till 17c.; then altered, perhaps by influence of relieve, etc. To believe on instead of in was more common in 16c. but now is a peculiarity of theology; believe of also sometimes was used in 17c.

belittle (v.)youdaoicibaDictYouDict
1781, "to make small," from be- + little (v.); first recorded in writings of Thomas Jefferson (and probably coined by him), who was roundly execrated for it in England:
Belittle! What an expression! It may be an elegant one in Virginia, and even perfectly intelligible; but for our part, all we can do is to guess at its meaning. For shame, Mr. Jefferson! ["European Magazine and London Review," 1787, reporting on "Notes on the State of Virginia"; to guess was considered another barbarous Yankeeism.]
Jefferson used it to characterize Buffon's view that American life was stunted by nature, which he was refuting. The figurative sense of "depreciate, scorn as worthless" (as the reviewers did to this word) is from 1797. Related: Belittled; belittling.
belive (v.)youdaoicibaDictYouDict
Old English belifan "remain," intransitive form of belæfan "cause to remain" (see beleave). A general Germanic word (cognates: Gothic beleiban, Old High German biliban, German bleiben, Dutch blijven); confused in early Middle English with beleave and merged into it, which gave beleave two clashing senses ("to leave," also "to remain") which might be why the compound word, the cognate of important verbs in other Germanic languages, was abandoned in English and only leave (v.) remains.
bell (n.)youdaoicibaDictYouDict
Old English belle, common North Sea Germanic (cognates: Middle Dutch belle, Middle Low German belle) but not found elsewhere in Germanic (except as a borrowing), from PIE root *bhel- (4) "to sound, roar." Statistical bell curve was coined 1870s in French. Of glasses in the shape of a bell from 1640s. Bell pepper is from 1707, so called for its shape. Bell, book, and candle is a reference to a form of excommunication. To ring a bell "awaken a memory" (1934) is perhaps a reference to Pavlovian experiments.
