She was born in 1871 in Novohrad-Volynskyi as Larysa Petrivna Kosach-Kvitka, to a well-off landowning family with intellectual, artistic and social traditions (her mother, Olena Petrivna Kosach, was also a writer and critic, while her father was a lawyer). Lesya’s childhood was marked not only by comprehensive intellectual and creative development (she published her first poem ‘Hope’ at the age of 9), but also by a serious illness – tuberculosis was a drain on her lungs, bones and kidneys. Incurable at the time, she often travelled to health resorts in Poland and abroad, including Egypt, Greece, Georgia and Italy.
It may be that these palliative travels to warmer and drier places contributed both to the development of her linguistic skills and her increased interest in other cultures. Thanks to her knowledge of French, Latin, Greek, Italian, German and English, she was able to become acquainted with the canon of European literature and was well acquainted with contemporary literary life.
These circumstances greatly influenced the artistic shape of the writer’s work, who other than Ivan Franko, made the greatest contribution to the modernisation of Ukrainian literature, developing it and leading it beyond the conventions of narrow regionalism.
The above is what Tadeusz Chrościelewski wrote about the importance of her linguistic skills. He also described of Larysa Kosach as ‘so Ukrainian and European at the same time’.
