"dark brownish-gray color" (the color of moleskin), 1906, from French taupe, the color, originally "a mole," Old French, from Latin talpa "a mole." The story below lacks evidence and appears to be a fanciful attempt to divert the origin of the color name to something more appealing:
Before the season advances very far you will find that taupe, pronounced "tope," will be the most favored color in the entire category of shades and blendings. The original word is taken from the German word "taube" pronounced "tob-a," which is the name for the dove, but the French have twisted the b into a p and give us taupe.

Taurus (n.) Look up Taurus at Dictionary.com
zodiac constellation, late Old English, from Latin taurus "bull, bullock, steer," also the name of the constellation, from PIE *tau-ro- "bull" (source also of Greek tauros, Old Church Slavonic turu "bull, steer;" Lithuanian tauras "aurochs;" Old Prussian tauris "bison"); from PIE *tauro- "bull," from root *(s)taeu- "stout, standing, strong" (source also of Sanskrit sthura- "thick, compact," Avestan staora- "big cattle," Middle Persian stor "horse, draft animal," Gothic stiur "young bull," Old English steor); extended form of root *sta- "to stand, make or be firm."

Klein proposes a Semitic origin (compare Aramaic tora "ox, bull, steer," Hebrew shor, Arabic thor, Ethiopian sor). De Vaan writes: "The earlier history of the word is uncertain: there is no cognate in [Indo-Iranian] or Tocharian, whereas there are Semitic words for 'bull' which are conspicuously similar. Hence, it may have been an early loanword of the form *tauro- into the western IE languages." Meaning "person born under the sign of the bull" is recorded from 1901. The Taurid meteors (peaking Nov. 20) so called from 1878.

And when his godship would again Taurise?

"I know of a surety that I deservedly bear the weight of my trouble on my neck, for I remember that, when I was a young maiden, I bore on it the needless weight of necklaces; and therefore I believe the Divine goodness would have me endure the pain in my neck, that so I may be absolved from the guilt of my needless levity, having now, instead of gold and pearls, the fiery heat of a tumour rising on my neck."

tea (n.) Look up tea at Dictionary.com
1650s, tay, also in early spellings thea, tey, tee and at first pronounced so as to rhyme with obey; the modern pronunciation predominates from mid-18c. But earlier in English as chaa (1590s), also cha, tcha, chia, cia. The two forms of the word reflect two paths of transmission: chaa is from Portuguese cha, attested in Portuguese from 1550s, via Macao, from Mandarin (Chinese) ch'a (cf chai). The later form, which became Modern English tea, is via Dutch, from Malay teh and directly from Chinese (Amoy dialect) t'e, which corresponds to Mandarin ch'a.

The distribution of the different forms of the word in Europe reflects the spread of use of the beverage. The modern English form, along with French thé, Spanish te, German Tee, etc., derive via Dutch thee from the Amoy form, reflecting the role of the Dutch as the chief importers of the leaves (through the Dutch East India Company, from 1610). Meanwhile, Russian chai, Persian cha, Greek tsai, Arabic shay, and Turkish çay all came overland from the Mandarin form.

First known in Paris 1635, the practice of drinking tea was first introduced to England 1644. Meaning "afternoon meal at which tea is served" is from 1738. Slang meaning "marijuana" (which sometimes was brewed in hot water) is attested from 1935, felt as obsolete by late 1960s. Tea ball is from 1895.
