A prie-dieu (French: literally, “pray [to] God”, plural prie-dieux) is a type of prayer desk primarily intended for private devotional use, but may also be found in churches. It is a small, ornamental wooden desk furnished with a thin, sloping shelf for books or hands, and a kneeler.

Oh! Thank you. I’m used to the English— a “kneeler” (although that is hardly exact for the shelf styled type).
I thought “prie-dieu” might be a movement or gesture. I see now that one might not be “offered” a gesture.
