Jordann is of Hebrew origin, meaning 'flowing down, descending'. It's a unisex name but is more commonly used for females. Jordann is often spelled without the middle 'e', differentiating it from Jordan, which also means 'descending' but has different origins and associations.
"The name Jordann has seen a steady increase and decrease in popularity over the past few decades, with peaks occurring around the mid-1990s and again from 2009 to 2014."
