Сегодня – Международный день родного языка. Мой родной язык – Русский! Я горд моим родным языком даже если я не использую его каждый день.
Today – 21st of February – is the International Mother Language Day. My mother language is Russian! I am proud of my mother language, even if I do not get to use it every day.
Apart from Russian, I know reasonably good English and have dabbled in French, Esperanto and – now – Spanish. I feel that starting from Russian, many other European/Germanic languages are easier, because Russian has a very complex grammar system with its conjugation and cases, tenses and moods. This helps with relating features of other languages to the examples in the one(s) I already know. This, of course, does not help at all with pronunciation, which for me is now atrocious in whichever language I speak.
Studying Spanish, I do find omitted pronouns in Spanish, but even that has its equivalence in Russian. Unfortunately, there is no equivalence for conflating conjugation for he/she and you (él/ella y usted). Using accents to differentiate words is a bit confusing too (él y el, qué y que). I am sure as I progress in Spanish, these things will become the second (3rd? 5th?) nature, but for now they do grate a bit.
I find Esperanto the easiest language of all, which is not very surprising, since it was specifically designed to be really easy. If I had to design a language from scratch, I don’t think I would be able to come up with anything significantly simpler than Esperanto, while still addressing the real use.
