Endings: conjugation & declension
FoundationsfreeThe heart of German grammar: words change their ending depending on their role in the sentence. English barely does this anymore (he walks, two dogs — that's almost all). German does it constantly. A word consists of a stem (the fixed part) and an ending (the changing part): geh|en, geh|st, klein|er, klein|es.
Conjugation — verbs change
Conjugation means: the verb adapts its ending to the acting person and to the time. *ich gehe (I go), du gehst (you go), er geht (he goes)* — same stem “geh”, three endings. Only verbs conjugate.
Declension — everything around the noun changes
Declension means: articles, adjectives, pronouns (and sometimes the noun itself) change form based on three factors: gender (the noun's class: der/die/das), number (singular or plural), and case (the role in the sentence — subject, object, etc.). Each factor gets its own unit; here you only need the idea: one word, many forms — the ending carries the information.
The C-test deletes the back half of the word — which is almost always exactly the ending. The stem is given, the ending is missing: “klein__”, “geh__”, “d__”. Endings decide your score, more than vocabulary breadth. That is exactly why this course is structured the way it is.
