= P =
pessimal /pes'im-l/ adj.
[Latin-based antonym for
`optimal'] Maximally bad. "This is a pessimal situation."
Also `pessimize' vt. To make as bad as possible. These words are
the obvious Latin-based antonyms for `optimal' and `optimize',
but for some reason they do not appear in most English
dictionaries, although `pessimize' is listed in the OED.
