AugustyoudaoicibaDictYouDict
August: [OE] The month of August was named by the Romans after their emperor Augustus (63 BC–14 AD). His name was Caius Julius Caesar Octavian, but the Senate granted him the honorary title Augustus in 27 BC. This connoted ‘imperial majesty’, and was a specific use of the adjective augustus ‘magnificent, majestic’ (source of English august [17]); it may derive ultimately from the verb augēre ‘increase’ (from which English gets auction and augment).
=> auction, augment
caesarianyoudaoicibaDictYouDict
caesarian: [17] The application of the adjective caesarian to the delivery of a baby by surgical incision through the abdomen and womb arises from the legend that Julius Caesar (c. 100–44 BC) himself or an earlier ancestor of his was born in this way. The name Caesar comes from the Latin phrase a caeso mātrisūtere, literally ‘from the mother’s cut womb’ (caesus was the past participle of the Latin verb caedere ‘cut’, from which English gets concise, incise, precise, etc). The abbreviation caesar for ‘caesarian section’ is mid 20th-century.

frank: [13] To call someone frank is to link them with the Germanic people who conquered Gaul around 500 AD, the Franks, who gave their name to modern France and the French. After the conquest, full political freedom was granted only to ethnic Franks or to those of the subjugated Celts who were specifically brought under their protection. Hence, franc came to be used as an adjective meaning ‘free’ – a sense it retained when English acquired it from Old French: ‘He was frank and free born in a free city’, John Tiptoft, Julius Caesar’s commentaries 1470.

In both French and English, however, it gradually progressed semantically via ‘liberal, generous’ and ‘open’ to ‘candid’. Of related words in English, frankincense [14] comes from Old French franc encens, literally ‘superior incense’ (‘superior’ being a now obsolete sense of French franc), and franc [14], the French unit of currency, comes from the Latin phrase Francorum rex ‘king of the Franks’, which appeared on the coins minted during the reign of Jean le Bon (1350–64).

The Franks, incidentally, supposedly got their name from their preferred weapon, the throwing spear, in Old English franca.

JulyyoudaoicibaDictYouDict
July: [13] July was the month in which Julius Caesar was born. Originally in ancient Rome it was called Quintilis, literally ‘fifth month’ (the Roman year began in March), but after the death and deification of Caesar its name was changed in his honour. Latin Jūlius passed into English via Anglo-Norman julie, and until the 18th century the word was usually pronounced to rhyme with truly (as the related woman’s name Julie still is).

masc. proper name, from Latin augustus "venerable" (see august). The name originally was a cognomen applied to Gaius Julius Caesar Octavianus as emperor, with a sense something like "his majesty."
German (n.)youdaoicibaDictYouDict
"a native of Germany," 1520s, from Latin Germanus (adjective and noun, plural Germani), first attested in writings of Julius Caesar, who used Germani to designate a group of tribes in northeastern Gaul, of unknown origin. Probably originally the name of an individual tribe, but Gaulish (Celtic) origins have been proposed, from words perhaps originally meaning "noisy" (compare Old Irish garim "to shout") or "neighbor" (compare Old Irish gair "neighbor"). Middle English had Germayns (plural, late 14c.), but only in the sense "ancient Teuton, member of the Germanic tribes." The earlier English word was Almain (early 14c.; see Alemanni) or Dutch.
Þe empere passede from þe Grees to þe Frenschemen and to þe Germans, þat beeþ Almayns. [John of Trevisa, translation of Higdon's Polychronicon, 1387]
Their name for themselves, die Deutschen (see Dutch), dates from 12c. Roman writers also used Teutoni as a German tribal name, and writers in Latin after about 875 commonly refer to the German language as teutonicus (see Teutonic). Meaning "the German language" in English is from 1748. High German (1823 in English) and Low German as a division of dialects is geographical: High German (from 16c. established as the literary language) was the German spoken in the upland regions in southern Germany, Low German (often including Dutch, Frisian, Flemish), also called Plattdeutsch was spoken in the regions near the North Sea. In the U.S. German also was used of descendants of settlers from Germany.
