The velar nasal, also known as agma, from the Greek word for 'fragment', is a type of consonantal sound, used in some spoken languages. It is the sound of ng in English sing. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ŋ⟩, and the equivalent X-SAMPA symbol is N. The IPA symbol ⟨ŋ⟩ is similar to ⟨ɳ⟩, the symbol for the retroflex nasal, which has a rightward-pointing hook extending from the bottom of the right stem, and to ⟨ɲ⟩, the symbol for the palatal nasal, which has a leftward-pointing hook extending from the bottom of the left stem. Both the IPA symbol and the sound are commonly called 'eng' or 'engma'.
