Some interesting origins
GOON: is derived from the Hindi goonda (hoodlum), and is now popularly accepted in English to denote a ruffian or thug.
GOSPEL: means "god spell". Since God once meant "good" and spell meant "news", gospel referred to the good tidings that the Christ child had been born.
GYMKHANA: surprisingly has nothing to do with gymnastic activities. Every major city in British India had its gymkhana club where the sporting types would gather on evenings and weekends. It is a modification from the Hindi word gendkhana meaning "a place for ball games"
GYMNASIUM: In ancient Greece all physical exercise were done in the nude. The sheltered areas where a number of people exercised in the nude was called a gymnasium, from the Greek word gymos, meaning "naked"
