The spelling of the biblical name "Abishua" can be explained using the International Phonetic Alphabet (IPA) transcription. The first syllable, "A", is pronounced as "ə", a neutral vowel sound. The letter "b" represents the voiced bilabial plosive "b", followed by the "sh" sound, phonetically transcribed as "ʃ". The second syllable is pronounced as "u", like the sound in "put". Finally, the letter "a" is pronounced as "ɑː", a back vowel sound. Therefore, the correct spelling of this name is Abishua.
The name Abishua is of Hebrew origin. It is derived from the Hebrew name Avishua, which consists of two elements: avi meaning my father and shua meaning wealth or salvation. Therefore, the name Abishua can be translated as my father is salvation or my father is wealth.
