Gha is the fourth consonant of Indic abugidas. In modern Indic scripts, gha is derived from the Brahmi letter , which is probably derived from the Aramaic ("H/X") after having gone through the Gupta letter .
- घ [gʱə] = 4 (४)
- घि [gʱɪ] = 400 (४००)
- घु [gʱʊ] = 40,000 (४० ०००)
- घृ [gʱri] = 4,000,000 (४० ०० ०००)
- घॢ [gʱlə] = 4×108 (४०८)
- घे [gʱe] = 4×1010 (४०१०)
- घै [gʱɛː] = 4×1012 (४०१२)
- घो [gʱoː] = 4×1014 (४०१४)
- घौ [gʱɔː] = 4×1016 (४०१६)
Gha (घ) is the fourth consonant of the Devanagari abugida. In all languages, घ is pronounced as [gʱə] or [gʱ] when appropriate. Letters that derive from it are the Gujarati letter ઘ and the Modi letter 𑘑.
Kagaa [kə̀gːɑ] (ਘ) is the ninth letter of the Gurmukhi alphabet. Its name is [kʰəkʰːɑ] and pronounced as /kə̀/. To differentiate between consonants, the Punjabi tonal consonant kà is often transliterated in the way of the Hindi voiced aspirate consonants gha although Punjabi does not have this sound. It is derived from the Laṇḍā letter gha, and ultimately from the Brahmi ga. Gurmukhi kagaa does not have a special pairin or addha (reduced) form for making conjuncts, and in modern Punjabi texts do not take a half form or halant to indicate the bare consonant /k/, although Gurmukhi Sanskrit texts may use an explicit halant.
Gha (ઘ) is the fourth consonant of the Gujarati script. It is derived from 16th century Devanagari letter dha (ध) with the top bar (shiro rekha) removed. Like most Gujarati letters, it forms conjunct clusters with a half-form, where the vertical stem on the right is dropped and the remaining letter body appended to the following letter. ઘ (gha) is similar in appearance to ધ (dha).
Kho ra-khang (ฆ) is the sixth letter of the Thai script. It falls under the low class of Thai consonants. In IPA, kho ra-khang is pronounced as [kʰ] at the beginning of a syllable and is pronounced as [k̚] at the end of a syllable. The second and third letters of the alphabet, kho khai (ข) and kho khuat (ฃ), are also named kho, however, they all fall under the high class of Thai consonants. The fourth and the fifth letters of the alphabet, kho khwai (ค), kho khon (ฅ), and kho ra-khang (ฆ), are also named kho and fall under the low class of Thai consonants. Unlike many Indic scripts, Thai consonants do not form conjunct ligatures, and use the pinthu—an explicit virama with a dot shape—to indicate bare consonants. In the acrophony of the Thai script, ra-khang (ระฆัง) means ‘bell’. Kho ra-khang corresponds to the Sanskrit character ‘घ’.
