Learn Turkish: Çözüm bulmak için birbirimizle iletişim kuruyoruz. - We communicate with each other to find a solution.

It comes from the reciprocal pronoun birbiri (each other). First, we add the 1st person plural possessive suffix -miz to match the 'we' of the sentence. Then we add the 'with' suffix -le. So birbirimizle means 'with each other'.

Why do we need the 'our' suffix (-miz) on birbiri? Doesn't it already mean 'each other'?

In Turkish, 'each other' has to reflect exactly who is interacting. If 'we' are interacting, it becomes birbirimiz (literally 'our each other'). If 'you' (plural) are interacting, it becomes birbiriniz. Since the main verb is kuruyoruz (we establish), we must use the -miz ending here.

Why is the verb kuruyoruz used here for 'communicate'?

The word iletişim means 'communication.' In Turkish, you don't usually use a single verb for 'to communicate'; instead, you 'establish communication.' The verb kurmak means to establish, build, or set up. So iletişim kurmak is the standard phrase.

Why does için come right after the full infinitive bulmak?

When you want to say 'in order to do something,' you use the infinitive form of the verb (ending in -mak or -mek) followed immediately by için. Here, bulmak için translates to 'in order to find.'
