Perfectly good: a rant.

Why is it that when in English someone describes something as perfectly good they mean it's only adequate and completely undesirable?

I mean, why????

…

Sometimes I think I'll never get the hang of this speaking English thing...

Words To Use Today: perfectly good. Perfect comes from the Latin word perfectus, from perficere, to perform, from per, through, and facere to do. The Old English form of good was gōd.
