Questions & Answers about Wir suchen eine Kamera.
Why is the article eine used here instead of einen or ein?
The verb suchen requires its direct object (the thing you are looking for) to be in the accusative case. Because Kamera is a feminine noun, its accusative article is eine. Feminine and neuter nouns don't change their indefinite articles in the accusative; only masculine nouns change (from ein to einen).
Where is the word for "for" in this sentence?
The verb suchen translates to "to look for" or "to search for". You don't need an extra word for "for" in German because it is already built into the meaning of suchen.
If I want to say "We look for a camera" instead of "We are looking", do I change the verb?
No, the sentence stays exactly the same. German doesn't have a separate "-ing" tense (present continuous) like English does. Wir suchen translates to both "We look" and "We are looking" depending on the context.
How would I change this sentence to say we are not looking for a camera?
You would replace the indefinite article eine with the negative article keine. The sentence becomes: Wir suchen keine Kamera. (Literally: We are looking for no camera).
