Questions & Answers about Welche Linie hält hier?
Why does welche end in -e here?
Welche is a question word that changes its ending to match the noun it describes, just like a definite article (der, die, das). Since Linie is a feminine noun in the nominative case (it is the subject of the sentence doing the stopping), welche takes the feminine nominative ending -e, acting just like die.
Does Linie mean any kind of line, like a line of people waiting?
No, in this context, Linie specifically refers to a public transit route, like a bus line (Buslinie) or tram line. If you want to talk about a line of people waiting, you would use the word Schlange (which literally means snake). A line drawn on a piece of paper is a Strich.
Why is the verb conjugated as hält and not haltet?
The verb halten (to stop, to hold) is a strong (irregular) verb. In the present tense, it has a vowel change from a to ä for the du and er/sie/es forms. Because welche Linie is a third-person singular subject (equivalent to sie), the verb takes the umlaut and becomes hält.
