You take the last letter, lets use bed, 'sek', if you want to make beds, you take the last letter, k, repeat it and add an e, so it ends up as sekke. But lets say you have a double vowel at the end of the word, pelniir, pencil, then you take out one of the two vowels, then repeat the previous steps, giving you pelnirre. If it ends in a vowel, you leave the vowel -even if there are 2 or 1- and add 'he' onto the end, zahkrii, zahkriihe.
