The German present participle refers to the present tense and has the ability to turn a verb into an adjective.

Building the German ‚Partizip I‘ is pretty easy:
You take the infinitive form of the verb – and take away the ending -en.
Then add a new ending: -end

When translating these forms into English, we use the present progressive.

Take a look at these examples:
spielen (to play) → spielend (playing)
sprechen (to talk) → sprechend (talking)
