Kokoro means insect in Yoruba and Cucaracha cockroach Spanish Do the words have a common Arabic root?

You are mistaken about the meaning of "kokoro" in Yoruba. "Kokoro" is not a Yoruba word and doesn't mean "insect." It is actually a Japanese word meaning "heart" or "mind."

The Yoruba word for insect is "erin."

While both "erin" (Yoruba) and "cucaracha" (Spanish) refer to insects, and both languages have some loanwords from Arabic, there is no evidence that these two words share a common Arabic root.

Here's why:

* Yoruba is a Niger-Congo language and has a distinct linguistic history. It's unlikely that a word for insect would be borrowed directly from Arabic.

* "Cucaracha" is likely derived from the Latin word "coccineus", which refers to a type of beetle. While Arabic may have influenced Spanish vocabulary, it's more likely that "cucaracha" has a Latin root.

It's important to rely on reliable sources and linguistic analysis when looking for etymological connections between words.
