miroir

Miroir is masculine. While it does derive from Latin "mirari" (to wonder at), the etymological path and gender assignment are more complex than stated. The word comes from Old French "mireor," which developed from Latin "miratorium" (a place for looking/wondering). However, the masculine gender of "miroir" is primarily due to the -oir ending in French, which is a productive masculine suffix derived from Latin -orium (neuter in Latin, but reanalyzed as masculine in Old French). The gender was not simply "retained" from Latin but rather reassigned through morphological reanalysis of the suffix pattern.
