The spelling of "llah" may cause confusion for non-Arabic speakers because it uses a combination of letters that are not present in the English language. The correct spelling in Arabic is الله and is pronounced as /Allāh/ in IPA phonetic transcription. The two letters "ll" represent a glottal stop, which is a consonantal sound produced by blocking and releasing the airflow in the vocal tract. The letter "h" represents a voiceless pharyngeal fricative sound, which is pronounced at the back of the throat. Together, these sounds create the Arabic word for God.
