Der is the nominative masculine singular definite article, so Der Rucksack is in the nominative case. It’s the subject of the sentence.
Why is Rucksack masculine?
In German, every noun has a grammatical gender (masculine, feminine, or neuter). Rucksack is simply one of the masculine nouns. There’s no foolproof rule—gender must be learned with each noun or by memorizing common patterns (for example, many nouns ending in ‑ack are masculine).
Why doesn’t leicht take an ending like ‑er, ‑e, or ‑es?
Here leicht is a predicate adjective following the linking verb ist. Predicate adjectives in German are not declined—they remain in their base form. Only attributive adjectives (those directly before a noun) carry endings.
Why is ist placed in the second position in Der Rucksack ist leicht?
