Well a few posts back I proposed that the appropriate definition of "are" is "is modelled by", since modelling is all we ever do in theoretical physics. The only question then is whether you can be arsed to say, for example, "momentum is modelled by the eignenvalues of the Hermitian operator p." Or whether you say "momentum is a Hermitian operator"...
Either way people generally know what is meant.
