Allahumma in Arabic is a vocative form with no ascertainable plural morphology or meaning. In comparative Semitic terms, an "m" indefiniteness marker or plural ending in languages like Hebrew corresponds to an "n" indefiniteness marker or plural ending in languages like Arabic (the mimation/nunation contrast). For these reasons, the Allahumma connection remains somewhat speculative. Many Arabists might say that Allahumma is "energic", and leave it at that... AnonMoos 07:50, 30 June 2007 (UTC)
