also Hell, Old English hel, helle, "nether world, abode of the dead, infernal regions, place of torment for the wicked after death," from Proto-Germanic *haljō "the underworld" (source also of Old Frisian helle, Old Saxon hellia, Dutch hel, Old Norse hel, German Hölle, Gothic halja "hell"). Literally "concealed place" (compare Old Norse hellir "cave, cavern"), from PIE root *kel- (1) "to cover, conceal, save."
The English word may be in part from Old Norse mythological Hel (from Proto-Germanic *halija "one who covers up or hides something"), in Norse mythology the name of Loki's daughter who rules over the evil dead in Niflheim, the lowest of all worlds (nifl "mist"). A pagan concept and word fitted to a Christian idiom. In Middle English, also of the Limbus Patrum, place where the Patriarchs, Prophets, etc. awaited the Atonement. Used in the KJV for Old Testament Hebrew Sheol and New Testament Greek Hades, Gehenna. Used figuratively for "state of misery, any bad experience" at least since late 14c. As an expression of disgust, etc., first recorded 1670s.
To have hell break loose is from c. 1600. Expression hell in a handbasket is attested by 1867, in a context implying use from a few years before, and the notion of going to Heaven in a handbasket is from 1853, implying "easy passage" to the destination. Hell or high water (1874) apparently is a variation of between the devil and the deep blue sea. To wish someone would go to hell is in Shakespeare ("Merchant of Venice"). Snowball's chance in hell "no chance" is from 1931; till hell freezes over "never" is from 1832.

c. 1300, paie, "satisfaction, liking; reward, reprisal," from pay (v.), or else from Old French paie "payment, recompense," from paier. Meaning "money or other compensation given for labor or services performed, wages" is from late 14c. In Middle English the usual sense was "satisfaction": My pay meant "my liking;" God's pay was "God's good will."
c. 1200, paien, "to appease, pacify, satisfy, be to the liking of," from Old French paier "to pay, pay up" (12c., Modern French payer), from Latin pacare "to please, pacify, satisfy" (in Medieval Latin especially "satisfy a creditor"), literally "make peaceful," from pax (genitive pacis) "peace" (see peace).
The meaning "to give what is due for goods or services" arose in Medieval Latin and was attested in English by early 13c.; the sense of "please, pacify" died out in English by 1500. Figurative sense of "suffer, endure" (a punishment, etc.) is first recorded late 14c. Meaning "to give or render" with little or no sense of obligation (pay attention, pay respects, pay a compliment) is by 1580s. Meaning "be remunerative, be profitable, yield a suitable return or reward" is by 1812. Related: Paid; paying. To pay up was originally (mid-15c.) "make up the different between two sums of money;" the sense of "pay fully or promptly" is by 1911. Pay television is attested by 1957.
