Zweierreihen in German?

Question

What a strange word. What does it mean? The sentence was something like Er stellt die in Zweierreihen auf.

Answer 1

The sentence was most probably: Er stellt sie in Zweierreihen auf.
It means you order a group of people two in a row - e.g. if a teacher makes an excursion with a class and wants them children to stay together when walking he lines them up two by two (if they are smaller they often hold the hand of the neighbour). I think that is common everywhere.
You can also make Dreierreihen oder Viererreihen of course but "Zweierreihen" are more practical.

Answer 2

The sentence translates literally as "It sets up in two-rows"
