Questions & Answers about Ya dışarı çıkalım ya da evde kalalım mı?
How does the phrase ya ... ya da work here? Can I just say ya ... ya?
ya ... ya da is a conjunction that means "either ... or". You can absolutely just use ya ... ya, but adding da to the second option is extremely common in Turkish and makes the contrast sound a bit more natural.
How do the verbs çıkalım and kalalım translate to "shall we"?
Both verbs use the 1st person plural "let's" suffix -alım / -elim. On its own, çıkalım means "let's go out". But when you add the question particle mı at the end of the sentence, it turns that "let's" statement into a question asking for the listener's opinion: "shall we?".
Why is the question particle mı only at the very end, rather than after both verbs?
When you connect two options in a single question, you usually only need to use the question particle once at the very end of the sentence. The mı here applies to the entire choice between çıkalım and kalalım.
Why doesn't dışarı have the directional "to" suffix (dative case) since we are going to the outside?
