When english speaking students learn Arabic and come across the word "cake" كَعْكٌ, they often assume it is borrowed from English.
In reality, it’s a totally different picture.
Classical scholars like Imām ar-Rāzī (d. 666 AH) noted in Mukhtār aṣ-Ṣiḥāḥ that
...kaʿk is an arabised word, likely borrowed from Persian, and originally referred to “ bread ” or “ dry bread .”
Meanwhile, the English word cake comes from Old Norse kaka — a completely different linguistic family.
So the similarity is just coincidence, not a shared origin.
Another reminder on importance to base conclusions on knowledge, not assumptions!
