Learn Turkish: Müdürün temassızlığı gidermesi için yeni bir kablo aldım. - I bought a new cable for the manager to resolve the loose connection.

When you want to say 'for [someone] to do [something],' Turkish uses a possessive construction. Because the person doing the action (the manager) is different from the person who bought the cable (I), you must use the genitive case on the subject (müdürün) and the possessive suffix on the verbal noun (giderme-si). It literally translates to 'for the manager's resolving.'

How does the word temassızlığı break down?

It comes from temas (contact). Adding -sız makes it 'without contact,' and -lık turns it into the noun temassızlık (lack of contact, or in electronics, a loose connection). Finally, the -ı at the end is the specific accusative suffix, because it is the direct object of the verb gidermek. Notice how the final k softens to ğ when the vowel is added.

What exactly does gidermek mean here? Is it related to gitmek?

Yes, historically it is a causative form of gitmek (to go), literally meaning 'to make something go away.' In modern Turkish, gidermek is commonly used to mean 'to resolve,' 'to eliminate,' or 'to relieve.' You will often see it used with problems (sorun gidermek), thirst (susuzluk gidermek), or in this case, a technical fault.

Why is it yeni bir kablo and not ?
