1. Learn alphabets through flashcards
When we were children, we always started learning alphabets through flashcards. The rule applies here also. There are different types of apps; some are free too, from which you can learn words and eventually sentences. However, as a trainer myself, I would recommend buying a book of Russian alphabets and a pocket dictionary. Though the Russian language has no similarity with English, you may find lots of loan words that you may find echoing English words. For example-
менеджер — manager
директор — director
маркетинг — marketing
компания — company
Интернет — internet
компьютер — computer
лаптоп — laptop
меню — menu
ресторан — restaurant
кафе — cafe
хот-дог — hotdog
бургер — burger
One word of caution would be that downloading apps like Lingoplay or Duolingo- they may give you a basic idea through gaming method or so but they do not have a personalized approach. More often than not, you will have to depend on your listening skills as far as pronunciation is concerned.
2. Handle Grammar one step at a time
For any language learning, Grammar is non-negotiable. However, there is a popular proverb- “don’t eat the elephant at one go”. Take one step at a time. Try to first familiarise yourself with the Russian culture by diving into their architecture, history and if you like to travel then Russia has a lot to offer. Immersing into language is way smarter than blindly following Grammar rules.
