Begadkefat
Begadkefat (also begadkephat, begedkefet) is the name given to a phenomenon of spirantization affecting the non-emphatic plosive consonants of Biblical Hebrew and Aramaic when they are preceded by a vowel and not geminated. The name is also given to similar cases of spirantization of post-vocalic plosives in other languages, for instance, in the Berber language of Djerba. Irish Gaelic has a similar system.
