Questions & Answers about Die Sonne erwärmt das Wasser.
Why is Die Sonne in the nominative case, and what role does it play in this sentence?
Die Sonne is the subject, i.e. the “doer” of the action. In German, the subject of a sentence always takes the nominative case. Since Sonne is a feminine noun, its nominative singular article is die.
Why is das Wasser in the accusative case?
Das Wasser is the direct object—the entity being warmed. German marks direct objects with the accusative case. For neuter nouns like Wasser, the nominative and accusative form of the definite article are both das.
How do I know that Wasser is neuter and thus takes das?
German nouns have grammatical gender (masculine, feminine or neuter). You simply have to learn each noun’s gender along with its article. Wasser is neuter, so it takes das in the nominative and accusative singular. A good dictionary entry will always list the gender, e.g. “das Wasser n.”
What tense and person is erwärmt, and how is this verb conjugated?
Erwärmt is the Präsens (present tense), third-person singular form of erwärmen. The infinitive is erwärmen (“to warm”), and with a singular subject like die Sonne you drop -en and add -t, giving erwärmt.
Why does the verb erwärmt appear in the second position in this sentence?
Standard German main-clause word order requires the finite verb to be in second position. Here, the first element is the subject (Die Sonne), so the verb (erwärmt) comes immediately after, followed by the object (das Wasser).
Why are nouns like Sonne and Wasser capitalized in German?
One of the rules of German orthography is that all nouns are always capitalized, no matter where they appear in a sentence. This helps distinguish nouns from other parts of speech.
What’s the difference between erwärmen, heizen, and erhitzen?
- erwärmen: to warm something up gently (raise temperature slightly).
- heizen: to heat (usually via a heating system, radiator, stove).
- erhitzen: to heat something intensely (often to a high temperature, e.g. water to boil).
In this context, the sun “gently warms” the water, so erwärmen is the most natural choice.
How can I express “The water is warmed by the sun” in German passive voice?
Use the Vorgangspassiv with werden plus the past participle. The sentence becomes:
Das Wasser wird von der Sonne erwärmt.
– Das Wasser (new subject in nominative)
– wird (3rd-person singular of werden)
– von der Sonne (agent introduced by von)
– erwärmt (past participle of erwärmen).
