Origin of tickety-boo
- I understand that the origin is India. In Hindi, "Tikai babu" means "It's alright, Sir." While India was governed under the British Empire, British airmen picked up the expression and it evolved into its current form. Canadian soldiers picked up the expression from their British allies during World War 2, and introduced it into Canadian jargon soon after.
