Ben toplantı kaydını sisteme yüklüyorum.

Ben toplantı kaydı-nı sistem-e yükle-yor-um.

• Ben: I (subject)
• toplantı: meeting
• kayıt → kaydı: “record/recording” with 3rd person possessive on the head of a noun compound (see below)
• -nı: accusative case (definite direct object)
• sistem: system
• -e: dative case “to”
• yükle: load/upload
• -yor: present continuous
• -um: 1st person singular

Turkish forms a compound “meeting recording” as an indefinite noun compound, where the head noun takes a 3rd person possessive marker:

• toplantı kaydı = meeting recording (compound; literally “meeting its-record”) When this compound is a definite object, it also takes the accusative:
• toplantı kaydı-nı = the meeting recording (as a definite object)

That -n- is a buffer consonant used when adding a case suffix to a noun that already has a possessive (or compound) suffix.

• kaydı (compound/possessed form) + -ı (accusative) → kaydı-n-ı.

Two things happen when adding the 3rd person possessive to kayıt:

• Consonant softening: final t → d before a vowel-initial suffix.
• Vowel harmony yields -ı here. So: kayıt → kaydı.

The verb yüklemek takes:

• the thing loaded in accusative: X-ı/‑i/‑u/‑ü
• the destination/target in dative: Y-a/‑e

So “upload X to Y” = X-i Y-e yüklemek. Vowel harmony picks -e after sistem (last vowel is front: e).

Present continuous is -(I)yor. With stems ending in -a/-e, that vowel drops and a high vowel appears before yor, chosen by vowel harmony based on the last remaining vowel of the stem.

• yükle- → drop final -e → last vowel is ü → pick high front rounded ü → yüklü-yor-um = yüklüyorum. Compare:
• bekle- → bekliyorum
• söyle- → söylüyorum
• başla- → başlıyorum

Yes. Turkish is flexible, and the element right before the verb is typically in focus.

• Neutral-ish: Ben toplantı kaydını sisteme yüklüyorum.
• Focus on destination: Ben toplantı kaydını SISTEME yüklüyorum.
• Focus on what’s being uploaded: Ben SİSTEME toplantı kaydını yüklüyorum. All are grammatical; stress and context signal what you’re highlighting.

Yes, that’s the “definite” noun–noun construction (with genitive on the first noun):

• toplantı kaydı = meeting recording (compound, more generic label)
• toplantının kaydı = the recording of the meeting (explicit “of the meeting”) Both can be definite as objects when you add accusative: … kaydını. Choose the genitive form when you want to explicitly mark the “of X” relation.

Drop the accusative on the object:

• Toplantı kaydı yüklüyorum. Accusative objects in Turkish are usually definite/specific. No accusative tends to signal an indefinite/unspecified object.

Yüklemek is broad: to load, upload, install, charge, assign. With tech:

• dosya(‑yı) sisteme/portala yüklemek = upload a file to the system/portal
• program(‑ı) bilgisayara yüklemek = install a program on the computer Context (and the target noun) disambiguates. For “install,” kurmak is also common for software.
