typhoon (n.) Look up typhoon at Dictionary.com
Tiphon "violent storm, whirlwind, tornado," 1550s, from Greek typhon "whirlwind," personified as a giant, father of the winds, perhaps from typhein "to smoke" (see typhus), but according to Watkins from PIE *dheub- "deep, hollow," via notion of "monster from the depths." The meaning "cyclone, violent hurricane of India or the China Seas" is first recorded 1588 in Thomas Hickock's translation of an account in Italian of a voyage to the East Indies by Caesar Frederick, a merchant of Venice:
concerning which Touffon ye are to vnderstand, that in the East Indies often times, there are not stormes as in other countreys; but euery 10. or 12. yeeres there are such tempests and stormes, that it is a thing incredible, but to those that haue seene it, neither do they know certainly what yeere they wil come. ["The voyage and trauell of M. Caesar Fredericke, Marchant of Venice, into the East India, and beyond the Indies"]
This sense of the word, in reference to titanic storms in the East Indies, first appears in Europe in Portuguese in the mid-16th century. It aparently is from tufan, a word in Arabic, Persian, and Hindi meaning "big cyclonic storm." Yule ["Hobson-Jobson," London, 1903] writes that "the probability is that Vasco [da Gama] and his followers got the tufao ... direct from the Arab pilots."

The Arabic word sometimes is said to be from Greek typhon, but other sources consider it purely Semitic, though the Greek word might have influenced the form of the word in English. Al-tufan occurs several times in the Koran for "a flood or storm" and also for Noah's Flood. Chinese (Cantonese) tai fung "a great wind" also might have influenced the form or sense of the word in English, and that term and the Indian one may have had some mutual influence; toofan still means "big storm" in India.
From the thighs downward he was nothing but coiled serpents, and his arms which, when he spread them out, reached a hundred leagues in either direction, had countless serpents' heads instead of hands. His brutish ass-head touched the stars, his vast wings darkened the sun, fire flashed from his eyes, and flaming rocks hurtled from his mouth. [Robert Graves, "Typhon," in "The Greek Myths"]
typhus (n.) Look up typhus at Dictionary.com
acute infectious fever, usually accompanied by prostration, delirium, and small reddish spots, 1785, from medical Latin, from Greek typhos "stupor caused by fever," literally "smoke," from typhein "to smoke," related to typhos "blind," typhon "whirlwind," from PIE *dheubh-, perhaps an extended form of root *dheu- (1) "to fly about like dust."
The Greek term [typhos] (smoke, mist, fog) was employed by Hippocrates to define a confused state of the intellect, with a tendency to stupor (stupor attonitus); and in this sense it is aptly applied to typhus fever with its slow cerebration and drowsy stupor. Boissier de Sauvages first (in 1760) called this fever "typhus," and the name was adopted by Cullen of Edinburgh in 1769. Previous to the time of de Sauvages typhus was known as "Pestilential" or "Putrid Fever," or by some name suggested by the eruption, or expressive of the locality in which it appeared, as "Camp," "Jail," "Hospital," or "Ship Fever" (Murchison). [Thomas Clifford, ed., "A System of Medicine," New York, 1897]

c. 1300, "absolute ruler," especially one without legal right; "cruel, oppressive ruler," from Old French tiran, tyrant (12c.), from Latin tyrannus "lord, master, monarch, despot," especially "arbitrary ruler, cruel governor, autocrat" (source also of Spanish tirano, Italian tiranno), from Greek tyrannos "lord, master, sovereign, absolute ruler unlimited by law or constitution," a loan-word from a language of Asia Minor (probably Lydian); Klein compares Etruscan Turan "mistress, lady" (surname of Venus).
In the exact sense, a tyrant is an individual who arrogates to himself the royal authority without having a right to it. This is how the Greeks understood the word 'tyrant': they applied it indifferently to good and bad princes whose authority was not legitimate. [Rousseau, "The Social Contract"]
Originally in Greek the word was not applied to old hereditary sovereignties (basileiai) and despotic kings, but it was used of usurpers, even when popular, moderate, and just (such as Cypselus of Corinth), however it soon became a word of reproach in the usual modern sense. The spelling with -t arose in Old French by analogy with present participle endings in -ant. Fem. form tyranness is recorded from 1590 (Spenser); Medieval Latin had tyrannissa (late 14c.).
