The spelling of the word "soha" can be explained using IPA phonetic transcription. The first letter "s" is pronounced as /s/, which is a voiceless alveolar sibilant sound. The following letter "o" represents the vowel sound /əʊ/ which is a diphthong sound pronounced as "oh". The last letter "h" represents an aspirated /h/ sound which means the sound is pronounced with a puff of air. Thus, the spelling of "soha" represents the sounds /səʊ.həʊ/.
The word "soha" does not have a well-documented etymology as it is not widely recognized as an English word. However, "soha" is a term used in Tibetan Buddhism that translates to "amen" or "may it be so" in English. It is often used at the end of a mantra or prayer, similar to how "amen" is used in Christian traditions. The origin of the term "soha" in Tibetan Buddhism is rooted in the ancient Tibetan language, but the exact etymology remains unclear.
