According to The Phrontistery (The Thinking Place) and their list of unusual words, lambert is a unit of brightness and light.
It was also the maiden name of my maternal grandmother (pictured above) who died recently after breaking her tailbone and having a heart attack as a result. She was 90 years old. Her oldest daughter, my mother, died at 42. My grandmother never quite recovered from losing her daughter so young and so the past 25 years have been hard on her.
I would like to celebrate the laughter and light I remember as a child visiting my grandmother by sharing this word of the day.
