Only one of them is Turkish. The other two are not.

Carlenson, your question in your website is wrong as none of those words are in Turkish.

Çakal ---> Farsi  ------>  Fa/OFa şaġāl شغال [this word passed into european languages from Farsi. 

Defter ---> Arabic  ---->  daftar دفتر  

Pencere ---> Farsi  ----> ~ Fa pancara/pancar پنجره/پنجر

Jackal entered English from Turkish "çakal" which is from Persian "shaghal".

jackal (n.)

c.1600, from Turk. çakal, from Pers. shaghal, from or cognate with Skt. srgala-s, lit. "the howler." Figurative sense of "skulking henchman" is from the old belief that jackals stirred up game for lions.

Which ever way it came from , it is originated from Persian and it does not change the fact that it is not a Turkish word.

TDK dictionary says it is "Persian" too.

Merhaba Turkish teachers should check words  on TDK website first  before they give quiz to learners, so that they wont go wrong.

I think that makes some difference. English loan is based on Turkish form "çakal" not "shaghal".

Take this one for example:

Turkish "Köşk" is from Persian

English kiosk is from Turkish "köşk"

Now kiosk entered Turkish as "kiosk"

Is it Persian or English? I would say it´s English.

Which ever way it came from , it is originated from Persian and it does not change the fact that it is not a Turkish word.

Regardless of where it originated from "çakal" is a widely recognized Türkish word now, just lie "telefon".
