The spelling of the word "elahe" is somewhat unusual in English, but it is actually a transliteration of a Persian name for God. The phonetic transcription of the word is /elɑːheɪ/, which reflects the way the word is pronounced in Persian. The "e" at the end of the word is not a separate syllable, but rather serves to elongate the preceding "a" sound. This spacing out of vowel sounds is a common feature of many languages.
The word "elahe" has its etymology in the Persian language. It is a feminine word derived from the Persian word "elāh" (اله), which means "god" or "deity". In Persian, "elahe" is often used to refer to a divine or celestial being, similar to an angel or a goddess.
