For those of you wondering why the name Sofia (and, introduced in the next lesson, Adamo) has been chosen: (from Wikipedia's page on Ludwik Lejzer Zamenhof, the creator of Esperanto)
Zamenhof and his wife Klara raised three children, a son, Adam, and two daughters, Sofia and Lidia. All three died in the Holocaust.
(Also: Sofia (with
f) is a rather common spelling of the name here in Europe, while Sophia (with
ph) probably is more common where English is the native language.)
(also: I'm just another komencanto, and have no insight on the addings of Lidia to the Duolingo course.)
It's Sophie in French, and it's written with φ (= ph) in Greek of course. The original meaning is "wisdom".
*Ĉu ĝi estas tre bela?
Ĝi estas tre bela, ĉu ne?
It deppends on context.
Is "u" a semivowel in "kiu"? What is the difference in pronunciation between "kiu" and "kiŭ"?
