Some truisms get long in the tooth;
Stale and hackneyed they become, "forsooth".
Dreary is a platitude
Which has lost all its attitude
Like a martini without any vermouth.

The AWAD today is "hackney" but the verb "hackneyed" is perhaps more common in everyday use. The other meaning of "hackney", after the horse which is used for routine riding and pulling carriages because of its agreeable gait, also gives us "hack". Per Anu: The word hack, in related senses, is a short form of hackney.

Hack comes from hackney, a horse
Which pulled coaches over a course.
Steady gait
What a fate!
A hack plods with endless remorse.
