A voiced velar plosive or stop is a type of consonantal sound used in many spoken languages.
Some languages have a voiced pre-velar plosive, which is articulated slightly more front compared with the place of articulation of the prototypical velar plosive, though not as front as the prototypical palatal plosive.
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.
The occlusion may be made with the tongue tip or blade ([t], [d]), tongue body ([k], [ɡ]), lips ([p], [b]), or glottis ([ʔ]). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in /m/ and /n/, and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.
Gaf (Persian: گاف; gāf), is the name of different Perso-Arabic letters, all representing /ɡ/. They are all derived from the letter kāf, with additional diacritics, such as dots and lines. In name and shape, it is a variant of kaf. It is also one of the five letters the Persian alphabet added to the Arabic alphabet (the others being ژ, پ, and چ in addition to the obsolete ڤ). Its numerical value is 5000 (see Abjad numerals). There are four forms, each used in different alphabets:
Gimel is the third (in alphabetical order; fifth in spelling order) letter of the Semitic abjads, including Phoenician gīml 𐤂, Hebrew gīmel ג, Aramaic gāmal 𐡂, Syriac gāmal ܓ Arabic jīm ج. Ancient North Arabian 𐪔, South Arabian 𐩴, and Ge'ez ገ.
Its sound value in the original Phoenician and in all derived alphabets, except Arabic, is a voiced velar plosive [ɡ]; in Modern Standard Arabic, it represents either a /d͡ʒ/ or /ʒ/ for most Arabic speakers except in Northern Egypt, the southern parts of Yemen and some parts of Oman where it is pronounced as the voiced velar plosive [ɡ].
