Learn Turkish: Sürücü anlık konum gönderdi, şimdi kargoyu teslim ediyor olacak. - The driver sent an instant location; he must be delivering the cargo now.

This is the epistemic use of the future tense. When combined with the present continuous -Iyor, the phrase ediyor olacak literally translates to 'will be delivering', but in Turkish, it's used for logical deductions about the present. It means 'must be delivering' or 'is probably delivering right now', based on the clue that he just sent his location.

Could I use teslim etmeli to say 'he must be delivering'?

No, because -mAlI usually expresses obligation or necessity ('he has to deliver'). When you want to say 'must' as a logical guess or deduction about an action happening right now, you need the -Iyor olacak structure.

Does anlık konum mean something specific in modern Turkish?

Yes! Anlık means 'instant' or 'momentary' (from an, meaning 'moment'), and konum is 'location'. Together, anlık konum is the standard term for 'live location' or 'current location', like the feature you use to share your location on a smartphone.

Why is it kargoyu and not just kargo?

The -(y)u suffix is the definite accusative case. The speaker is referring to a specific, expected package rather than just any general cargo. Because 'the cargo' is the definite direct object of the verb teslim etmek, it must take this ending.
