Объяснение:

Київ. Це коротке звучне слово – назва міста, корені якого йдуть глибоко в сиву давнину. Його історія нараховує більш ніж 1500 років. Це одне з найстаріших слов'янських міст - столиця ранньофеодальної держави Київська Русь, місто, відоме в історії як «мати міст руських». Один із центрів, де зароджувалася рання слов'янська культура як важлива складова світової цивілізації.

Київ оспівується в піснях, у безсмертному літописі «Повісті минулих літ» (друга половина ХІІ ст.), в епосі «Слово о полку Ігоревім», у романах, операх. Місто зробило величезний внесок у всесвітню історію, науку, культуру і мистецтво.

Kiev. This is a short sonorous word - the name of the city, whose roots go deep into ancient times. Its history is more than 1500 years old. It is one of the oldest Slavic cities - the capital of the early feudal state of Kievan Rus, a city known in history as the "mother of Russian cities". One of the centers where the early Slavic culture originated as an important component of world civilization.

Kyiv is glorified in songs, in the immortal chronicle "Tales of Past Years" (second half of the twelfth century), in the epic "A Tale of Igor's Regiment", in novels and operas. The city has made a huge contribution to world history, science, culture and art.
