Learn Icelandic: Hvar sérð þú veskið mitt?

mitt is the neuter, singular form of the possessive pronoun. It has to match the gender, number, and case of the noun it belongs to, which is veskið (the wallet). Since the wallet is the direct object of the sentence (the thing being seen), it is in the accusative case. Luckily, for neuter words, the accusative form of 'my' is exactly the same as the basic dictionary form: mitt.

Why does the noun have a 'the' ending (veskið) if we are saying 'my wallet'?

In Icelandic, you almost always put the definite article (the 'the' ending) on a noun when it is followed by a possessive pronoun. veski means 'a wallet', but to say 'my wallet', you must use the definite form veskið (the wallet) and put mitt right after it. It literally translates to 'the wallet my'.

How does the verb sjá (to see) become sérð?

sjá is an irregular verb, meaning it changes its vowels when conjugated. sérð is the specific form used for þú (you). While the vowel changes, the -rð ending is a very common pattern for the 'you' form in Icelandic verbs.

Why is the subject þú placed after the verb sérð?
