Gentilnesse, or Gentilnes seem to be the most common spellings.
This is the firs of a regular series of posts about the meaning behind Middle English words.
What is gentleness? Is it being kind to people? Does it mean talking quietly to them and not upsetting them.
The word didn’t really take on that meaning until about the 17th century. In the time of Chaucer the word mean that one acted in a way that was appropriate for someone of noble or gentle birth. I.e. you acted like a gentleman. That might mean one acted in a temperate and kind way, but that was the behaviour expected of a noble person or gentle birth and thus the meaning.
Here’s a good example from Chaucer’s Parsons Tale (I. 585):
“He seith hit cometh him of gentilnes of his auncetres.”
