Niggardly is said to be the mispronounced origin of the word Nigger or Niggard. Niggard is a very old word. The English meaning is “miser” or “stingy person.” Americans often mistakenly assume it is a variant on the most common insulting term for “African-American.”
The Spanish or Portuguese Negro meaning black or dark seem to be misspoken or misused to insult blacks and black slaves; some Irish where referred to as niggers too during those days.
So you see the term referred to salves or people that were not producing enough work according to the task master. The person that was not working hard enough was said to be a niggard or niggardly in his work habits.
Southerners back in slavery times and later where not the brightest stars in the sky when it came to their native language English; they either mispronounced the word or used it with intent to heap further abuse upon a people they considered not human and derive more work from them. A great number where worked to death.
Sad to say many black today do not know the origin of the term. They too misused it.
The Niggard only gave us 3 pence for that work!
I’m tried; I’m going to be niggardly about my work today.
Let that Niggard/Nigger know he got to work harder.
