The last letter tell us about personal pronoun. It means if you said " trinke tee" without "ich" I will under stand you are talking about your self because of "e" which tell us about personal pronoun ، and so on.

More explain : In English: she, he, it take "s" in verb ، I, they, you, we without "s"..

In Deutsch most verb in present take: --- Ich - e . * er, es, sie ( she ),ihr - t . * du - st . wir, Sie ( they ) - en.

I hope I could explain it ☺.. May Allah bless you ☺..

The verb "trinken" conjugated for the noun ich is trinke.

It's like telling ''I drinks tea.'' in English.Sounds awful,right?Think like you are Deutsch.

Because in German there's no present continuous. "I am drinking tea" is the same as "I drink tea". And you only translate "I drink tea" without the 'am'.

Verbs following the pronoun 'ich' usually end with the letter e.

that would be i drinking tea

Because der , das and die means in english (the) and her he is not write (the) and you will write without der
