Questions & Answers about Jag ska ha köpt fiolen och cellon innan helgen.
Why use ska ha köpt here instead of kommer att ha köpt?
Both translate to "will have bought", but ska implies a personal intention, plan, or promise. Using kommer att would sound more like a neutral prediction or statement of fact about the future.
Why is it köpt instead of the infinitive köpa?
Köpt is the supine form of the verb. To build the future perfect tense, you combine the auxiliary verbs (ska ha or kommer att ha) with the supine to express an action that will be completed before a certain time.
Cello is a loanword. How do you form its definite and plural forms in Swedish?
It acts as a standard en-word. Because it ends in a vowel, you just add -n for the singular definite (cellon). If you needed to talk about multiple cellos, the plural is cellor and plural definite is cellorna.
Can I say före helgen instead of innan helgen?
Yes, you can use them interchangeably here. Strictly speaking, före is a preposition (used before nouns) and innan is a conjunction (used before a whole clause). However, in modern everyday Swedish, innan is widely accepted as a preposition as well.
