We need to talk about how verbs are formed in the German language. Because it depends on the usage. For example, defined articles can change it. Der nette Herr, die nette Frau, das nette Ding. That was with defined articles. Undefined articles add a letter when in Nominative case. Ein netter Herr, eine nette Frau, ein nettes Ding.
I wanted to tell you that because of your username...
