ظ alphabetical letter ظ
The seventeenth letter of the alphabet: called ظَآءٌ
[and ظَا]. (TA.) It is a letter peculiar to the Arabic language; and is one of the letters termed مَجْهُورَة [or vocal, i. e. pronounced with the voice, not with the breath only]; and of the letters termed لِثَوِيَّة [or gingival], like ث and ذ. (TA.)
As it does not exist in the language of the Nabathæans, they change it into ط. (IF, TA.)
[It is substituted for the ت in the measure اِفْتَعَلَ and the forms inflected therefrom when immediately following ظ; as in اِظَّلَمَ, for اِظْظَلَمَ, for اِظْتَلَمَ:] and it is substituted for ذ; as in تَرَكْتُهُ
وَقِيذًا and وَقِيظًا; as is related on the authorities of ISk and Kr; and as in أَرْضٌ جِلْذَآءٌ and جِلْظَآءٌ, as is mentioned in the Nawádir el-Aaráb. (TA.)
A2: [As a numeral, it denotes Nine hundred.]
