What does the name Jennah mean?
Jennah is a spelling of Jenna, pronounced the same way, so it shares Jenna's meaning and origin.
Jenna is a form of Jenny and is usually a short form of Jennifer, according to Wiktionary. Jennifer is the Cornish form of Guinevere, the wife of King Arthur, from Welsh Gwenhwyfar. DMNES explains the Celtic elements of Guinevere as "white" and a word meaning phantom or spirit, so the name is often glossed "white phantom." Jenny can also be a pet form of Jane, so some Jennas go back to John's feminine forms instead.
Gwenhwyfar (Welsh, “Guinevere”)*windo (Proto-Celtic, “white”)*sēbro (Proto-Celtic, “phantom, spectre”)
How sure is this? Probable. Meaning depends on whether the family takes Jenna from Jennifer or from Jenny/Jane.
