‘Et al’ just is Latin jargon that doesn’t belong in the title of a blog post or a speech. It merely means ‘and others.’ That phrase belongs in a list of references at the end of a scholarly magazine article – where an article has more than three authors, so listing them all would be clumsy.
But in posts at her Speechwriter-Ghostwriter blog Jane Genova has used it seven times just this year. They were:
May 27, 2018: The psychotherapy brand – David W. Harder, et al.
May 2, 2018: Kathleen Huebner, et al. – No, I do not wish you well
April 17, 2018: The law, according to Jones Day, et al.
April 13, 2018: Tronc layoff – Why writers, et al., have such tough time exiting comfort zone
March 28, 2018: Thanh Cong Phan, et al. – perhaps they just wanted to be a “somebody”
February 27, 2018: Alexa, et al. – voice tech eliminating traditional brands, consumer choice
February 3, 2018: Unlike iGen, our tribe HAD TO meet up in-person – Charlotte Toal, M. Lynn Rickert, et al.
