What does yetkinliğini mean, and how is it built?

Yetkinliğini is a multi-part word:

• yetkinlik = competence, proficiency
• yetkinliği = his/her competence or their competence
• yetkinliğini = his/her competence as the definite direct object

So the structure is:

• yetkinlik
  • -i → yetkinliği
    This is the 3rd person possessive ending: his/her/their competence
• yetkinliği
  • -ni → yetkinliğini
    This adds the accusative marking, because it is the object of the verb gösterdi

Also note the sound change:

• yetkinlik → yetkinliği
• final k often becomes ğ before a vowel

So this one word means something like his/her technical competence in object form.

Why is there an -ni at the end of yetkinliğini instead of just yetkinliği?
