Questions & Answers about Sopiiko tämä uusi ajankohta sinulle?
Why is sinä in the allative case (sinulle) here?
The verb sopia (to suit, to fit) dictates that the person experiencing the suitability must be in the allative case (-lle). You can think of it literally as asking if the time is suitable to you.
What is the difference between ajankohta and just aika?
Aika means "time" in a broad, general sense (like time passing, or having free time). Ajankohta, however, specifically refers to a "point in time", "date", or "scheduled slot". When arranging meetings or appointments, ajankohta is the precise and natural word to use.
The current lesson also teaches käydä. Could I use it instead of sopia here?
Absolutely. You could say Käykö tämä uusi ajankohta sinulle? In the context of scheduling, käydä and sopia are essentially synonymous and both require the allative case (sinulle). Käydä is just a bit more colloquial, though very common in everyday speech.
Could I attach the question particle -ko to a different word, like Tämäkö uusi ajankohta sopii sinulle?
