This is an irregular feature - both in frequency and oddness - dedicated to a word I came across that I have never previously used.
vernissage (vehr-nih-SAHJ) n. Private preview of an art exhibition; the opening of an art exhibition.
Vernisage is derived from the French verb vernir ("to varnish"). One of the last tasks an artist might perform before the opening would be to varnish the finished work. The ceremonial ending of art exhibitions, for those who need to know, is called "finissage."
