The voiced velar fricative is a type of consonantal sound, used in various spoken languages.
Wikipedia says that it is not found in English today, but did exist in Old English.1
Why did this sound disappear? What happened in the history?
Some other Germanic languages still have that. Might it still exist in some dialects or casual speech in English?
Some relevant details1:
The symbol ɣ is also sometimes used to represent the velar approximant, though that is more accurately written with the lowering diacritic: [ɣ̞] or [ɣ˕]. The IPA also provides a dedicated symbol for a velar approximant, [ɰ], though there can be stylistic reasons to not use it in phonetic transcription
