Did you know, that knowing just 10 words gives you an opportunity to make 1000+ phrases?

Let’s select 10 words, and let’s suppose that we can use any of these words as many times as we need in a sentence. And, we also can use all prepositions, question words and the verb БЫТЬ - “to be” apart from these 10 words, because prepositions, question words and “to be” connect everything in a language.

Let’s consider an example.

САМОЛЁТ, ДОРОГА, МАШИНА, ЖЕНЩИНА, КНИГА, БОЛЬШОЙ, БЫСТРЫЙ, ТЕЛЕФОН, ПОКУПАТЬ, СМОТРЕТЬ

And let’s build phrases:

Самолёт был большой и женщина на машине купила телефон и книгу и смотрела на дорогу  The airplane was big and the woman in car bought a phone and a book and looked at the road

Самолёт быстрее чм машина, но женщина смотрела на машину в книге An airplane is faster than a car, but the woman looked at the car in the book.

Машина была большая но самолёт был быстрым The car is big but the airplane is fast.

Женщина купила телефон и смотрела на машину и большой самолёт The woman bought a phone and looked at the car and big airplane.

Some of these sentences look like nonsense, but this is just an exercise, and there is place for “grammatically correct nonsense” used for training. And you can make hundreds and thousands of phrases knowing just these 10 words and  using them with prepositions with question words and the verb “to be”. It is a good way to improve sentence building skills, skills of declension by cases, genders, plural/singular(depending of a language), conjugation of verbs. And also it will help to memorize these 10 words that you selected.
