I have noticed that appear reduces to a Latin parere
appear (v.) Look up appear at Dictionary.com late 13c., "to come into view," from stem of Old French aparoir (12c., Modern French apparoir) "appear, come to light, come forth," from Latin apparere "to appear, come in sight, make an appearance," from ad- "to" (see ad-) + parere "to come forth, be visible." Of persons, "present oneself," late 14c. Meaning "seem, have a certain appearance" is late 14c. Related: Appeared; appearing.
You see, they say that it stems from parere, which means to come forth or be visible. Yet, I see that this meaning of parere contrasts with readiness that is said to be meaning of the word when we look at the roots of the the other English words
preparation (n.) Look up preparation at Dictionary.com late 14c., "act of preparing," from Latin praeparationem (nominative praeparatio) "a making ready," noun of action from past participle stem of praeparare "prepare," from prae "before" (see pre-) + parare "make ready" (see pare). Meaning "a substance especially prepared" is from 1640s.
repair (v.1) Look up repair at Dictionary.com "to mend, to put back in order," mid-14c., from Old French reparer "repair, mend" (12c.), from Latin reparare "restore, put back in order," from re- "again" (see re-) + parare "make ready, prepare" (see pare). Related: Repaired; repairing.
How is that possible? Are the two meanings, be visible and ready, reducible to each other?
pare (v.) Look up pare at Dictionary.com "to trim by cutting close," c. 1300, from Old French parer "arrange, prepare; trim, adorn," and directly from Latin parare "make ready, prepare, furnish, provide, arrange, order; contrive, design, intend, resolve; procure, acquire, obtain, get; get with money, buy, purchase" (related to parere "produce, bring forth, give birth to"), from PIE *par-a-, suffixed form of root *pere- (1) "produce, procure, bring forward, bring forth," and derived words in diverse senses (source also of Lithuanian pariu "to brood," Greek poris "calf, bull," Old High German farro, German Farre "bullock," Old English fearr "bull," Sanskrit prthukah "child, calf, young of an animal," Czech spratek "brat, urchin, premature calf"). Generalized meaning "to reduce something little by little" is from 1520s. Related: Pared; paring.
