To be a precieuse was in itself an evidence of good conduct.
We find here the code which ruled the Hotel de Rambouillet, and the very well-defined character of the precieuse.
There was Ninon; and there was Madame de Rambouillet; the one galante, the other precieuse.
"pedantic woman, woman aiming at refined delicacy of language and taste" (1727), from French précieuse, noun use of fem. of précieux (see precious (adj.)); especially as lampooned in Molière's comedy "Les Précieuses ridicules" (1659).
