Friendliness → It is formed from "friend" (from Old English "freond", meaning a person with whom one has a bond of mutual affection) and "-liness" (meaning the quality of being). The word "friendliness" means the quality of being a friend or showing kindness and goodwill.
Think of a 'friend' as someone you have a bond with, and '-liness' indicates the quality of that bond. This helps you remember that friendliness is about the quality of being a good friend.
