Questions & Answers about Ben yazıcıyı bilgisayara bağlıyorum.

Why does yazıcı become yazıcıyı?

Because you’re marking yazıcı as a definite direct object. In Turkish, specific/definite objects take the accusative suffix -ı/-i/-u/-ü. Here:

1. yazıcı (printer)
2. add the buffer consonant y (because the word ends in a vowel)
3. add the accusative -ı
   → yazıcı
   • y
     • ı = yazıcıyı (“the printer”).

Why is bilgisayara in the “-a” form?

That’s the dative case (“to/into”). The verb bağlamak (“to connect”) takes its target in the dative. You form the dative by adding -a/-e to a noun (vowel-harmonized). So:
bilgisayar + a → bilgisayara = “to the computer.”

What tense/mood is bağlıyorum, and how is it formed?

bağlıyorum is 1st person singular present continuous (“I am connecting”). Formation steps:

1. Take the verb stem: bağla- (connect)
2. Add the continuous suffix -yor (harmonized to -ıyor after a back vowel)
3. Add the personal ending -um for “I”
   Result: bağla-
   • -yor
     • -um = bağlıyorum.

Why does the stem look like bağlı- instead of bağla- before -yorum?

When you attach -yor to bağla-, the vowel sequence a+y triggers a slight stem change for easier pronunciation:
bağla- + -yor → bağlıyor (3rd sg.)
Similarly for 1st sg.: bağlı- + -yorum → bağlıyorum. It’s just a natural result of vowel harmony and consonant/vowel sequencing.

Can I drop Ben in Ben yazıcıyı bilgisayara bağlıyorum?

Yes. Turkish verb endings already signal the subject. Bağlıyorum alone means “I am connecting.” You include Ben only if you want extra emphasis on “I.”

Is the word order flexible—could I say Bilgisayara yazıcıyı bağlıyorum?

Absolutely. The default is S O V (Subject-Object-Verb), but objects can swap for emphasis. Both these are correct and mean the same:
• Yazıcıyı bilgisayara bağlıyorum.
• Bilgisayara yazıcıyı bağlıyorum.

What’s the difference between bağlıyorum and bağlarım?

• bağlıyorum = present continuous (“I am connecting right now”).
• bağlarım = aorist/habitual (“I connect/usually connect” or a general statement). Use -yor for ongoing actions, -ar/-er for habitual/general ones.
