I'm not sure I understand your question. I can turn a verb into a noun by taking the infinitive form and adding "das". This noun describes the act of doing something. These nouns typically don't have a plural, because the act of doing something is abstract and can't have a plural. gehen -> das Gehen = going springen -> das Springen = jumping weben -> das Weben = weaving leben -> das Leben (no plural) = living Additionally, there are nouns that derive from a verb, with all sorts of genders (i.e. articles). These sometimes change the stem vowel, sometimes they don't. They often have plural forms. gehen -> der Gang | die Gänge = the walk | walks springen -> der Sprung | die Sprünge = the jump | jumps weben -> die Webe | die Weben = the weave | weaves leben -> das Leben | die Leben = the life | lives These are different constructions, not "nouns constructed with 'das' in the same way". Even if the article is "das" and the form is the same in both cases. Your last example exhibits these two constructions, this time with a different gender, and a slightly different form: falten -> das Falten = folding (the act) falten -> die Falte | die Falten = the fold, the crease | folds, creases
