Questions & Answers about Kurye iki saattir yolda, paketi şimdi teslim ediyor olacak.
How can olacak (future tense) be used with şimdi (now) in teslim ediyor olacak?
This is the core of epistemic expectation. Even though -AcAk is the future tense marker, when attached to olmak (to be) following another verb, it often expresses a strong logical deduction or assumption about the present. The speaker is saying, based on the fact that the courier has been on the road for two hours, I logically expect that he is delivering it right now.
What is the exact breakdown of the compound verb teslim ediyor olacak?
It combines the present continuous suffix -Iyor in ediyor (is delivering) with the future tense suffix -AcAk on the auxiliary verb olmak (will be). While literally it translates to "he will be delivering", in this context it acts as a present deduction: "he must be delivering". If you just used teslim edecek, it would simply mean "he will deliver" in the future, losing the sense of present deduction.
Could I use the necessity suffix -mAlI and say teslim etmeli instead?
You could, but the nuance shifts. Teslim etmeli usually implies an obligation or duty ("he is required to deliver the package"). Using ediyor olacak completely removes the idea of obligation and focuses purely on your logical assumption that the event is actively happening right at this moment.
