What is the root of word inspired?

The root of the word "inspired" is the Latin word "spirare", meaning "to breathe".

Here's how it breaks down:

* "spirare" (Latin) --> "inspiratus" (Latin, past participle) --> "inspired" (English)

The concept of "inspiration" was originally linked to the idea of breathing in divine breath or spirit. This is why the word "inspire" still carries a sense of divine guidance, creativity, or motivation.
