Deliver
Translation into plain English Transport
Perpetrator Royal Dutch Shell
Usage example "Royal Dutch Shell on Thursday said it was “in a delivery window for new growth” as it reported a substantial rebound in profits for the third quarter and rising production."
Lucy’s commentary Best Combination of Weasel Words 2010. The overused “deliver” and “window” – which are only acceptable when referring to something that can be transported in a van or to something you can see through – are combined by Royal Dutch Shell to create something entirely opaque.
