I recently heard this word used by a computer game reviewer, to mean “excessively powered”, “given too much power”.
Call me old fashioned, but I don’t like it one jot.
It’s a natural, if somewhat unfortunate, use of the prefix “over-” to mean excessively. Cf. “overclock.”
I remember, from some thirty years ago, “overpowered” used of a car with too powerful an engine for the suspension and brakes to cope with.
I would probably use the hapless hyphen to distinguish “overpowered” from “over-powered”. But I suppose that would be hopelessly oldfashioned.
(ed.) or, as OP Tipping says wittily, “old fashioned”
Not nearly as potentially confusing as “oversight”.
If you thought I was being witty, you overestimate me.
