A ridge or saddle-shaped point on a mountain or between two peaks (regional or geological term).
From Afrikaans 'nak' or Dutch 'nek,' borrowed into English through South African usage. Related to Germanic and Scandinavian words meaning neck or narrow passage, it describes a geographically narrow high point.
Geologists and mountaineers use 'nak' across Africa and parts of Asia, but it's largely unknown in English-speaking regions—it's a great example of how English borrows terms from local languages when newcomers encounter unfamiliar landscapes.
