Its source is a Hebrew expression meaning "Well spoken."
This girl's name is used in German, Dutch and English.
The name Oma ranked 1157th in popularity for females of all ages in a sample of the 1990 US Census.
The derivation given is very uncertain, and assumes this name is a female form of Omar.
However, among German and Dutch speakers this is an affectionate nickname for a grandmother, and an identical word in Finnish means ''home.'' A similar name derived from Sanskrit, Omana, means ''woman.''
Either by coincidence or linguistic evolution, these three meanings are obviously related, and somewhere in and around them the true meaning of this name may lie.
