What is it? Well, it's simply giving endearment to someone in name... a pet name, of sorts. Honey. My Love. Ernie-kins... to name a few hypocorisms.
As I'm thinking about hypocorisms, I'm finding myself remembering moments from childhood. My parents always called me "honey" when growing up, and my brother always called me "Doodles" since I always loved to doodle and draw pictures. He still calls me that to this day and I'm quite fond of it.
When I was a preschool teacher, I gave my kids little nicknames such as "kiddo" and "goober" for my silliest ones. To the quiet ones, "sweetie" and "little one," were favorites. For the most part, they didn't mind.
When we give someone a nickname or term of endearment, it shows affection and a doting attitude towards him or her. Even without thinking about it, you're telling the person that you care for him or her, which makes everyone feel good inside.
What sort of special nicknames do you give to your loved ones? What is one that you are called that you like?
