Questions & Answers about Ben şampuan kullanıyorum.

Why is ben optional in Ben şampuan kullanıyorum? Do I have to include it?

In Turkish the personal ending on the verb (here -um in kullanıyorum) already shows that the subject is “I.” You can safely drop ben and just say Şampuan kullanıyorum. Including ben is only needed for emphasis or contrast (e.g. “I, on the other hand, use shampoo”).

What tense or aspect is kullanıyorum, and how is it formed?

Kullanıyorum is the present continuous (progressive) form, literally “I am using.” It’s built as follows:

1. Root: kullan- (to use)
2. Progressive suffix: -ıyor (adjusted by vowel harmony to -uyor because the root’s last vowel is u)
3. Personal ending: -um (first person singular)
   Putting it together: kullan- + uyor + um = kullanıyorum (“I am using”).

Why doesn’t şampuan take an accusative ending like şampuanı?

Turkish marks definite, specific direct objects with the accusative ending. Since this sentence states the general action “I use shampoo” (not “I use the shampoo”), şampuan remains unmarked (nominative/indefinite). If you meant “I use the shampoo (that we bought),” you’d say Ben şampuanı kullanıyorum.

How would I say “We use shampoo” or “He/she uses shampoo”?

You just change the personal ending:
• (Ben) şampuan kullanıyorum – I use/am using shampoo
• (Sen) şampuan kullanıyorsun – You use/are using shampoo
• (O) şampuan kullanıyor – He/she uses/is using shampoo
• (Biz) şampuan kullanıyoruz – We use/are using shampoo
• (Siz) şampuan kullanıyorsunuz – You (pl./formal) use/are using shampoo
• (Onlar) şampuan kullanıyorlar (or kullanıyor) – They use/are using shampoo

How do I make the sentence negative: “I don’t use shampoo”?

Insert the negative suffix -ma- before the progressive -yor:

1. Root + negative: kullan-ma-
2. Progressive: -yor → adjusted to -muyor by vowel harmony
3. Personal ending: -um
   Result: kullanmıyorum.
   Full sentence: (Ben) şampuan kullanmıyorum – “I don’t use shampoo.”

How would I turn Ben şampuan kullanıyorum into a question (“Do you use shampoo?”)?

Attach the question particle -mı/-mi/-mu/-mü after the verb stem (before -yor) and then add the appropriate ending. For “you (singular)” it’s:
• Stem + ques. particle: kullan-ıyor musun
Add object and optional pronoun: (Sen) şampuan kullanıyor musun?
Literally: “You are using shampoo?” → “Do you use shampoo?”
