Learn Turkish: Ablam bilgisayar kullanmakta çok becerikli; bana gelince, ben oldukça tembelim. - My sister is very skillful at using computers; as for me, I am quite lazy.

It literally translates to "when it comes to me." It combines the dative pronoun bana (to me) with gelince, which is the verb gelmek (to come) plus the time suffix -(y)ince (when). This combination is the standard Turkish way to shift topics to a new person or thing, similar to "as for..." or "when it comes to..." in English.

Why is the locative suffix -ta attached to the infinitive in kullanmakta?

While English uses "at" for skills (like "skillful at using"), Turkish uses the locative case (-da / -de / -ta / -te) attached to the infinitive verb (-mak / -mek). This defines the specific action or area where someone has a certain skill or trait, translating literally to "skillful in using."

Since the sentence already says bana gelince, is it necessary to use the subject pronoun ben right after it?

It is grammatically optional because the personal suffix -im on tembelim already tells us the subject is "I". However, including ben right after bana gelince adds strong emphasis, sharply contrasting the speaker's laziness with their sister's skill.

Does the word oldukça come from the verb olmak?
