The lateral nasal click is a click consonant found primarily among the languages of southern Africa.
The symbol in the International Phonetic Alphabet for a nasal lateral click with a velar rear articulation is ⟨ŋ͡ǁ⟩ or ⟨ŋ͜ǁ⟩, commonly abbreviated to ⟨ŋǁ⟩, ⟨ᵑǁ⟩ or ⟨ǁ̃⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ŋ͡ʖ⟩ or ⟨ŋ͜ʖ⟩, abbreviated ⟨ŋʖ⟩, ⟨ᵑʖ⟩ or ⟨ʖ̃⟩. For a click with a uvular rear articulation, the equivalents are ⟨ɴ͡ǁ, ɴ͜ǁ, ɴǁ, ᶰǁ⟩ and ⟨ɴ͡ʖ, ɴ͜ʖ, ɴʖ, ᶰʖ⟩.
Sometimes the accompanying letter comes after the click letter, e.g. ⟨ǁŋ⟩ or ⟨ǁᵑ⟩; this may be a simple orthographic choice, or it may imply a difference in the relative timing of the releases.[1]
