Nushki drew from two Balochi words "Nosh-Koh" which stands for finishing work. In fact from 852 till 1764, the ancient Baloch tribe Mandai was ruling over Nushki. In 1546-47, Mandai along with Rakhshani tribes including Jamaldini, Hooth, Badini, Jeehandzai, Makaki, Lajahi and Badozai fought against Kamaran Mirza the brother of Naseer u Deen Hummyaun, where they defeated Mughals under the leading of Mir Mandai Khan and Mir Bijar Khan. When they backed from battle field, people asked them "What happened? They answered, we finished them", means (Nosh-Koh) with the passage of time, this word converted in "Nushki".
