We prove a local normal form theorem of the Gaifman type for the infinitary logic LβˆžΟ‰(Q u ) Ο‰ whose formulas involve arbitrary unary quantifiers but finite quantifier rank. We use a local Ehrenfeucht-FraΓ―ssΓ© type game similar to the one in [9]. A consequence is that every sentence of LβˆžΟ‰(Q u ) Ο‰ of
