"drink made from the ground and roasted seeds of a tree originally native to Arabia and Abyssinia," c. 1600, from Dutch koffie, from Turkish kahveh, from Arabic qahwah "coffee," which Arab etymologists connected with a word meaning "wine," but it is perhaps rather from the Kaffa region of Ethiopia, a home of the plant (coffee in Kaffa is called būno, which itself was borrowed into Arabic as bunn "raw coffee").
The early forms of the word in English indicate a derivation from Arabic or Turkish: chaoua (1598), cahve, kahui, etc. French café, German Kaffe are via Italian caffè.
The first coffee-house in Mecca dates to the 1510s; the beverage was in Turkey by the 1530s. It appeared in Europe c. 1515-1519 and was introduced to England by 1650. By 1675 the country had more than 3,000 coffee houses and coffee had replaced beer as a breakfast drink, but its use there declined 18c. with the introduction of cheaper tea. In the American colonies, however, the tax on tea kept coffee popular.

c. 1200, from Old Norse geta (past tense gatum, past participle getenn) "to obtain, reach; to be able to; to beget; to learn; to be pleased with," a word of very broad meaning, often used almost as an auxilliary verb, also frequently in phrases (such as geta rett "to guess right"). This is from Proto-Germanic *getan (source also of Old Swedish gissa "to guess," literally "to try to get"), from PIE root *ghend- "to seize, take."
Old English, as well as Dutch and Frisian, had the verb almost exclusively in compounds (such as begietan, "to beget;" forgietan "to forget"). Vestiges of an Old English cognate *gietan remain obliquely in modern past participle gotten and original past tense gat, also Biblical begat.
In compound phrases with have and had it is grammatically redundant, but often usefully indicates possession, obligation, or necessity, or gives emphasis. The word and phrases built on it take up 29 columns in the OED 2nd edition; Century Dictionary lists seven distinct senses for to get up.
"I GOT on Horseback within ten Minutes after I received your Letter. When I GOT to Canterbury I GOT a Chaise for Town. But I GOT wet through before I GOT to Canterbury, and I HAVE GOT such a Cold as I shall not be able to GET rid of in a Hurry. I GOT to the Treasury about Noon, but first of all I GOT shaved and drest. I soon GOT into the Secret of GETTING a Memorial before the Board, but I could not GET an Answer then, however I GOT Intelligence from the Messenger that I should most likely GET one the next Morning. As soon as I GOT back to my Inn, I GOT my Supper, and GOT to Bed, it was not long before I GOT to Sleep. When I GOT up in the Morning, I GOT my Breakfast, and then GOT myself drest, that I might GET out in Time to GET an Answer to my Memorial. As soon as I GOT it, I GOT into the Chaise, and GOT to Canterbury by three: and about Tea Time, I GOT Home. I HAVE GOT No thing particular for you, and so Adieu." [Philip Withers, "Aristarchus, or the Principles of Composition," London, 1789, illustrating the widespread use of the verb in Modern English]
