well you guys were no help. what happened to the usual 30 second reply?

kidding!!

spent far too much time surfing it out, but I found it, and if it helps anyone else:

x-height = Hauteur d’x
baseline = Ligne de pied
and
Bold = Gras

cheerios,
-t

I had wanted to learn these myself. I learned a few by comparing the english and french versions of Porchez's site, but I'm sure that they will not be much of a surprise:

roman = romain
italic = italique
titling = titrage

I'd also be interested in learning the rest.

My French is limited to ordering food and catching taxis in Paris even though I worked in Paris La Defense for a while.

Maybe this link to LEXIQUE TYPOGRAPHIQUE might be helpful.

Also, these seems like a good jump points to other sites about typography in French:
Typographie.org
Planete-Typographie.com

Yes, I'm old, but I'm back in style!

According to the still-evolving ATypI
multi-lingual terminology project:

x-Height is:
"hauteur des bas de casse"

and

Baseline is:
"ligne de base"
or
"ligne d'écriture"
