divan: [16] The word divan has a long and spectacularly variegated semantic history. It started out as Persian dēvān, which originally meant ‘small book’. This came to be used specifically for ‘account book’, and eventually for ‘accountant’s office’. From this its application broadened out to cover various official chambers and the bodies which occupied them, such as tax offices, customs collectors, courts, and councils of state.

And finally it developed to ‘long seat’, of the sort which lined the walls of such Oriental chambers. The word carried these meanings with it via Arabic dīwān and Turkish divān into the European languages, and English acquired most of them as a package deal from French divan or Italian devano (it did not, however, include the ‘customs’ sense which, via the Turkish variant duwan, survives in French douane, Italian dogana, Spanish aduana, etc).

The 19th-century sense ‘smoking lounge’ seems to be an exclusively European development.

ball (n.1)youdaoicibaDictYouDict
"round object," Old English *beal, from or corresponding to Old Norse bollr "ball," from Proto-Germanic *balluz (cognates: Old High German ballo, German Ball), from PIE root *bhel- (2) "to blow, inflate, swell" (see bole).

Meaning "testicle" is from early 14c. Ball of the foot is from mid-14c. A ball as an object in a sports game is recorded from c. 1200; To have the ball "hold the advantage" is from c. 1400. To be on the ball is 1912, from sports. Ball-point pen first recorded 1946. Ball of fire when first recorded in 1821 referred to "a glass of brandy;" as "spectacularly successful striver" it is c. 1900.
katzenjammer (n.)youdaoicibaDictYouDict
1849, "a hangover," American English colloquial, from German katzen, comb. form of katze "cat" (see cat (n.)) + jammer "distress, wailing" (see yammer). Hence, "any unpleasant reaction" (1897).
Pleasure can intoxicate, passion can inebriate, success can make you quite as drunk as champagne. The waking from these several stages of delights will bring the same result--Katzenjammer. In English you would call it reaction; but whole pages of English cannot express the sick, empty, weary, vacant feeling which is so concisely contained within these four German syllables. ["Blackwood's Edinburgh Magazine," August 1884]
Katzenjammer Kids "spectacularly naughty children" is from title of comic strip first drawn by German-born U.S. comic strip artist Rudolph Dirks (1877-1968) in 1897 for the "New York Journal." It was temporarily de-Germanized during World War I:
"THE SHENANIGAN KIDS" is the new American name for the original "Katzenjammer Kids." Although the original name and idea were pure Holland Dutch, some people may have had the mistaken impression that they were of Germanic origin, and hence the change. It is the same splendid comic as in the past. [International Feature Service advertisement in "Editor & Publisher," July 6, 1918]
