Questions & Answers about Die Lösung ist simpel.

Why is die used before Lösung instead of der or das?

Because Lösung is a feminine noun in German. In the nominative singular, all feminine nouns take the definite article die.

Why is simpel not declined here? Shouldn't German adjectives change their endings?

When an adjective follows a linking verb like ist (to be), it functions as a predicate adjective and remains in its base (undetermined) form without any endings. Only attributive adjectives (those placed directly before a noun) get declined.

How would you use simpel as an attributive adjective modifying Lösung?

Attributive adjectives must agree in gender, number, and case with the noun they describe. Since Lösung is feminine singular in the nominative:

• You would write die simple Lösung, where simple carries the weak ending -e after the definite article.

What’s the difference between simpel and einfach? Are they interchangeable?

Both words mean “simple” or “straightforward,” but:

• einfach is more common and neutral.
• simpel can sound more colloquial or even slightly negative, suggesting something is overly simplistic or crude. In many contexts you can swap them, but be aware of the subtle tone difference.
