Satyagraha an English Word?

I was under the impression that Satyagraha is an Indian Word. Apparently I am wrong. Satyagraha is also an English word because....

Justin Song a 13 year old 8th Grader from Carmen Valley Middle School, San Diego, California was asked to spell "Satyagraha" in round 10 of National Spelling Bee Competition. Unfortunately Justin was eliminated because he misspelt the world Satyagraha as Sattyagraha.

From Wikipedia

Satyagraha (Sanskrit: सत्याग्रह satyāgraha) is a philosophy and practice of nonviolent resistance developed by Mohandas Karamchand Gandhi (also known as "Mahatma" Gandhi). Gandhi deployed satyagraha in campaigns for Indian independence and also during his earlier struggles in South Africa.

Maybe in the 82nd National Spelling Bee someone will be asked to spell "Gandhigiri" :-)
