Questions & Answers about Min kniv är vassare än din.
How do we get the form vassare (sharper)?
Vassare is the comparative form of the adjective vass (sharp). For regular adjectives in Swedish, you just add -are to the end of the base word to compare things, which is very similar to adding "-er" in English.
What word do we use for "than" in Swedish comparisons?
The word is än. Whenever you use a comparative adjective like vassare, you pair it with än to say "than", matching the English comparison pattern perfectly.
Why is it din at the end of the sentence instead of ditt?
Din refers back to the noun it replaces, which is kniv (knife). Because en kniv is an en-word, the possessive word has to match it and be din. If you were talking about an ett-word, you would use ditt.
Does din mean "your" or "yours" here?
In this sentence, it translates to "yours". Swedish doesn't have a separate set of words for "yours", "mine", or "ours". You just use the standard possessive words (min, din, etc.) whether they are followed by a noun or stand completely alone at the end of a sentence.
