 Regular German verbs follow this pattern in the present tense:
 
-*   {ich lerne} = I learn, am learning
+*   {ich lerne}
-*   {er lernt}, {es lernt}, {sie lernt} = he learns, it learns, she learns

-Both "I learn" and "I am learning" are represented in German by {ich lerne}.
+German uses a single verb form for both ongoing and habitual actions — for example, {ich lerne} covers both meanings.

 $GRAMMAR Grammar: Indirect Objects
 INTRO: Let's learn about indirect objects in German.
 
-In a sentence like "The instructor gives the student the book" or "The instructor gives the book to the student", "the book" is the direct object and "(to) the student" is the indirect object. In German, the "der" or "ein" word (including "kein" and possessives) in front of an indirect noun object appears in a special form. When preceding a "der" or "das" noun, it takes the ending "-em", when preceding a "die" noun, it takes the ending "-er".
+German has a special form for indirect objects (dative case). In {Der Lehrer gibt dem Schüler das Buch}, {das Buch} is the direct object and {dem Schüler} is the indirect object.
