Sikha
The sikha or shikha (; IAST: śikhā; "crest"; Hindi चोटी (choTi)) means flame, powerful, peak of a mountain. It is a name of Hindu / Indian origin, and is commonly used for females. It also means long tuft, or lock of hair, left on top or on the back of the shaven head of a male Orthodox Hindu. Though traditionally all Hindus were required to wear a śikhā, today it is seen mainly among Brahmins and temple priests.
