What do you call your partner—darling, sweetheart, babe? I have been called a little owl, a swan and even a “panda-fish.” No, I’m not a supernatural, shape-shifting creature or a character in a children’s storybook. I’ve just been in a few relationships where affectionate nicknames appeared as inside jokes.

Plenty of my friends have developed nicknames with their romantic partners. I asked the question on Facebook and got all kinds of answers: former boyfriends who knew each other as “Tiger and Teddy.” An American man who dated a Chinese woman told me he called her “Popo”, which means “wife” or “broken broken,” depending on your intonation and she called him “Benben,” which he says means something like “dumb dumb,” referring to his poor mastery of the Chinese language at the time.

There seems to be a variety of languages with pet names, too. According to the website of the popular language-learning software Rosetta Stone, the French say “Mon Petit Chou” (my little cabbage or cream puff), the Russians say “Vishenka” (cherry), the Dutch call girlfriends “Dropje” (candy) and in Brazil you can say “Meu Chuchu,” where “chuchu” is a vegetable. In Spain I heard the term “Media Naranja,” meaning half-orange, suggesting that the romantic partners are two halves of the whole.

Is there any science behind using pet names? Is it a mark of a healthy relationship, or unhealthy? Are couples who give each other names, ranging from the generic “Honey” and “Sweetie” to the creative “Loopy Lop,” more likely to stay together? And in our digital age, are these nicknames any more important?

From what has been studied, and from the experience of several experts, it seems nicknames can be a good thing for a relationship—if both partners are into it.
