Learn Hardcore German: Mein Ticket ist kleiner als dein Buch.

Possessive pronouns (mein, dein) function as determiners and replace the article. In the nominative singular for neuter nouns (like Ticket and Buch), they remain in their basic form without additional endings.

Why is als used here instead of wie?

German distinguishes unequal and equal comparisons:

als is used for unequal comparisons (“smaller than”),
wie is used for equal comparisons (“as small as”).
Since a ticket and a book are being compared as different in size, you use als.

Is dein Buch in the nominative or accusative case, and how can I tell?

It’s in the nominative case. After a comparative with als, the second term stays in the case it would have if it were simply the subject (here it’s not acting as an object of the verb). Both nominative and accusative forms of neuter singular are identical, but logically it’s nominative.

Why isn’t there a comma before als?

No comma is needed when als introduces just a noun phrase for comparison. A comma is only required if als starts a full subordinate clause with its own conjugated verb (e.g., Mein Ticket ist kleiner, als ich dachte.).

Why is the verb ist in the second position in the sentence?

German main clauses follow the V2 (verb-second) rule: the finite verb must occupy the second position, regardless of how many words or phrases come before it. Here, Mein Ticket is first, and ist comes second.

Could you say Mein Ticket ist kleiner als dein Buch ist?

Yes, but it’s redundant. Adding the second ist turns als dein Buch ist into a subordinate clause, which is grammatically correct but unnecessarily wordy. Native speakers usually omit the final ist.

Why are German nouns like Ticket and Buch always capitalized?

Orthographically, German requires all nouns to begin with a capital letter, regardless of their position in a sentence. This rule helps distinguish nouns from other parts of speech.
