IPA: /ˈfrɛndliər/
KK: /ˈfrɛndliər/
More kind and pleasant than someone or something else.
She is friendlier than her sister when meeting new people.
Friendlier → It is formed from "friend" (from Old English "freond", meaning a person with whom one has a bond of mutual affection) and "-lier" (a comparative suffix indicating more of a quality). The word "friendlier" means more friendly or showing a greater degree of friendship.
Think of a 'friend' as someone you have a bond with, and when you add '-lier', it means you are showing more of that bond. So, friendlier means being more like a friend.
