How can ´ring´ and ´steal´ be the same verb? No logical connection at all.

and "to play" too

radyoda arabesk bir şarkı çalıyor...

Does it have to be a logical connection for eşsesli kelimeler?

The cliche example, yüz means:

• a hundred
• face
• to swim (root of yüzmek)
• to skin (take the skin from body)

How should we try to catch the ´connection´ between these words?

Çalmak also means vurmak "to hit",  as you can see in the sentence "al da başına çal" 

Also there is another meaning of çalmak let me explain it with and example: "onun gözlerinin rengi yeşile çalıyor"  means color of his eyes is not exactly green but something similar to green

I also think it is not coincidental: one syllable verb roots hardly just lapse together.

One possible explanation is foreign influence. The corresponding verb in Arabic or Persian may have a range of meanings and these may have been transferred from language to language by bilingual speakers.

You are right Abla, I checked an etymological dictionary and it says "to play" meaning of çalmak comes from Persian because according to the dictionary, "to play the guitar" is something like "to hit the guitar" in Persian

Oh I am sorry then I didn´t know that it means sürmek in that example. So it seems çalmak has a lot of meanings

Yes - this is one of many things that I always wanted to ask but somehow didn´t

Does this mean that "gitarı çalıyorum" can mean both "I am playing guitar" and "I am stealing the guitar" ? Is there any way to differentiate between both meanings in Turkish?
