"Variant of Tahani"
The name Tehani is commonly a female name from the "Urdu" origin.
Tehani is a transliteration variant of Tahani, a feminine given name used in Arabic-speaking countries. Both spellings render the same Arabic word, tahani, the plural of tahni'a, which carries the sense of congratulation or good wishes. The difference between the two spellings is one of transliteration into Latin letters, not a difference of name or meaning.
Tahani means "Congratulations".
The pronunciation of Tehani is teh-HAH-nee.
