One of friends send me a message. I don't understand a word in his message. This message is as follow:
*I am curios about why are you studying the Wells turbine?
What is the exact meaning of "curios"?
Rover_KE is correct your friend meant curious however you might be intrested to know curios is a word.
It is the plural of curio meaning a rare or unusual object.
