Questions & Answers about Ben raporu sisteme yüklüyorum.

Why is it raporu and not rapor?

Turkish marks a definite/specific direct object with the accusative suffix -(y)I. Since "the report" is specific, rapor becomes raporu. The last vowel of rapor is o, so vowel harmony picks -u.

• Indefinite object: sisteme rapor yüklüyorum or sisteme bir rapor yüklüyorum ("I am uploading a report").
• Definite object: raporu sisteme yüklüyorum ("I am uploading the report").

What does sisteme mean and why the ending -e?

-e/-a is the dative case, marking direction/goal ("to/into/onto"). sistem + -e → sisteme because the last vowel is front unrounded, so choose -e. Compare:

• sistemde (locative, -de/-da): "in/on the system"
• sistemden (ablative, -den/-dan): "from the system"
