In European languages, including German, a verb has six kinds of conjugations based on the subject.
For example, you say in English;
I drink, you drink, he/she/it drinks, we drink, etc.
And you say the same words in German;
ich trinke, du trinkst, er/ihr/es trinkt, wir trinken, etc.
German verbs end with "en," and you conjugate to correspond with the ending.
Dr. Wilhelm Roentgen from Germany is the famous inventor of the X-ray. Using his name, we say, "take a Roentgen" in Japanese, which means "take an X-ray."
The funny thing I learned is that in German, his name conjugates like;
ich roentge, du roentgest, er/ihr/es roentget, wir roentgen, etc.
Can it be changed because it ends with "en"!? It would be like as if you were to say in English;
I dicken, you dicken, he/she/it dickens, we dicken etc., to mean you created a great literary writing.
