Questions & Answers about Ben pasaportumu gümrükte gösteriyorum.

Why is ben included in Ben pasaportumu gümrükte gösteriyorum when it’s often omitted in Turkish?

The verb ending -um in gösteriyorum already indicates “I.” Native speakers frequently drop ben unless they want:
• Emphasis (“I, not someone else, am doing this”).
• Contrast (“I’m showing it, but he isn’t”).
• Extra clarity in complex sentences.
You can freely say Pasaportumu gümrükte gösteriyorum for a perfectly natural “I’m showing my passport at customs.”

What do the two suffixes -um and -u mean in pasaportumu, and why are they both there?

In pasaportumu you see:

1. pasaport (passport)
2. -um = 1st person singular possessive (“my passport”)
3. -u = accusative case marker showing that the object is definite (“the passport,” not just any passport).
   So the layering is pasaport-um (my passport) + ‑u (the direct object is specific).

Why is the object marked with the accusative case here? In English we don’t add a special ending for “my passport.”

Turkish marks definite direct objects with -ı/-i/-u/-ü (vowel-harmonized). If you’re showing “a passport” (indefinite), you’d often drop the accusative: Pasaport gösteriyorum (“I’m showing a passport”). But when it’s your known, specific passport, you use the accusative: pasaportumu.

In the sentence we have gümrükte, but could we say gümrüğe instead?

They mean different things:
• gümrükte = at/in customs (locative case)
• gümrüğe = to customs (dative case)
Since you want to say “I’m showing my passport at the customs desk,” you need the locative -te suffix.

What does the suffix -te in gümrükte express, and why isn’t it -de or -da?

-de/-da is the locative marker (“at/in”). Because gümrük ends in the voiceless consonant k, the initial d of the suffix becomes its voiceless counterpart t (a regular consonant-assimilation rule). Vowel harmony also picks e (the front unrounded vowel), so you get gümrük-te.

Why is gösteriyorum used (the progressive) instead of the simple present tense?

Turkish distinguishes:
• –(I)r for habitual/general truths (“I show passports [as a job]”).
• -iyor for actions happening right now.
Since you’re doing it at this moment in customs, you need the progressive gösteriyor-um (“I am showing”).

Can I move the word order, for example say Gümrükte pasaportumu gösteriyorum or Pasaportumu gümrükte gösteriyorum?

Yes. Turkish is fairly flexible with S-O-A-V order (Subject-Object-Adverbial-Verb). Shifting elements only changes emphasis:
• Gümrükte pasaportumu gösteriyorum (focus on the location)
• Pasaportumu gümrükte gösteriyorum (neutral)
The core meaning stays the same as long as the case endings and verb form stay intact.

Where is the English preposition “at” in Turkish? I don’t see a separate word for it in gümrükte.

Turkish uses case-ending suffixes instead of independent prepositions. The idea of “at” or “in” is built into the -de/-da suffix. So gümrükte literally means “in/at customs” without needing another word.
