Questions & Answers about Vet du vem som gömde glasögonen?
Why is there a som after vem in this sentence?
This is a rule for indirect questions! When the question word (like vem or vad) is the subject of the indirect question, you must add som after it. If we just asked a direct question, we would say Vem gömde glasögonen? But because it is embedded inside the phrase Vet du..., it becomes Vet du vem som gömde glasögonen?
Would I still use som if the indirect question was about the object instead of the subject?
No! You only add som when the question word is the subject (the one doing the action). For example, if you ask 'Do you know who I saw?', it translates to Vet du vem jag såg? Here, jag is the subject of the second clause, so vem is just the object, and you do not use som.
Why does the word for glasses, glasögonen, look so long?
It is a compound word made of glas (glass) and ögonen (the eyes). So it literally translates to 'the glass eyes'! It is a plural definite noun, meaning 'the glasses', just like in English.
Is gömde in the past tense?
Yes, gömde is the past tense of gömma (to hide). It is a group 2 verb, which means it takes -er in the present tense (gömmer) and adds -de to the root to form the past tense.
