The directly attested Old Turkic form is çekürgä, whereas *çekürtke is a comparative reconstruction based on the widespread later -rtk- forms. Clauson notes that this pronunciation may be original although it is not the oldest recorded form. In Kāšgarī, Oghuz çekürgä denotes a locust, while another Turkic usage refers specifically to a locust before it flies, i.e. a hopper or nymph.
