The name that is transliterated as «Hadassah» in English means «myrtle.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines the signs for “myrtle” and points to the traditional attire worn by women, who covered their mouths with a veil. (Source: Missão Kophós )
