Every two words in the line are regular expressions and unix. How?

Question

Regular Expressions

Please help me write a regular expression that selects every two words and uses the sed command to move them to the next line.
I wrote an example for one word, of course I understand that this is a kindergarten, I just haven’t come across them yet.
\n will be inserted after each word followed by a space. Thus, when displayed, it will be on the next line.
sed 's/ /\n/g' mytext.txt

Answer 1

I don’t know exactly how to achieve this in niks, but a regular expression that will split words into pairs: [a-z]+\s[a-z]+
Although judging by the date you have already found the answer to your question)
