How do you spell "do"?
The spelling of prefixes in the Russian language causes a lot of difficulties due to the fact that they are often written and heard in completely different ways. Most often it concerns words with prefixes on c (s). And how do you spell “do”?
The word “make” is formed from the verb “make” with the help of the prefix “c”. Therefore, this word is written, firstly, in one piece. And secondly, those who have doubts in writing should memorize a simple rule: in Russian there is no prefix "z".
There will always be disagreements who will object: After all, there are similar words, and they are written with the letter “3”! Yes, these words are: building, great, here. Often they are called exceptions, but this is not true. “Z” in these words is part of the root, not a prefix.
But why is it so obvious to hear “z” in the word “do”? There is an explanation for this riddle. After the deaf "s" is ringing "d". Because of this, the prefix is voiced, that is, it sounds like a sonorous sound.
But in this case, the basic rule applies: the subsequent consonant has no effect on the spelling of the prefix "c".
Therefore, there should not even be a question about how to spell “do”.The answer is only one - "make".
