How do you say rainbow in Inca language?

There is no single word for "rainbow" in the Inca language, Quechua.

Instead, it's described with a phrase: "Arco Iris".

This is because Quechua, like many indigenous languages, uses descriptive phrases rather than singular words for certain concepts.

Here's a breakdown of the phrase:

* Arco: This word is borrowed from Spanish and means "arch."

* Iris: This is also borrowed from Spanish and means "iris" or "rainbow."

So, "Arco Iris" literally means "arch of the iris," which is a poetic way to describe a rainbow.
