Learn German: Ich lerne. - I am learning.

German does not have a separate continuous tense like English does. The single word lerne translates to both "learn" and "am learning". You just use the standard present tense for both situations!

Why does the verb end in -e?

In German, the ending of a verb changes to match the person doing the action. When the subject is ich (I), regular verbs take an -e at the end.

How do we get from the dictionary form to lerne?

The dictionary form of the verb is lernen (to learn). To use it with ich, you drop the -en ending to get the stem lern-, and then attach the -e ending.

The lesson mentions the V2 rule for word order. Does this two-word sentence follow it?

Yes! The V2 rule means the conjugated verb is always the second piece of information in a normal statement. Here, ich is position 1, and the verb lerne is position 2.
