Pet names are more or less unavoidable. Even if you have an agreement in your relationship to avoid calling each other "honey" or "baby," it's likely one of you will fall into the trap at some point.

Research has shown that using cutesy terms could be a result of your mother using them with you. Pet names are essentially a form of baby talk, which help infants learn languages while expressing love at the same time.

More good news is having adorable pet names for each other is a sign your relationship is strong.

People all over the world make up affectionate names for each other, some of which sound quite strange when they are directly translated to English.

Language experts at Babbel looked into alternative pet names from around the world and found they vary quite a lot.

Katja Wilde, Head of Didactics at Babbel, told Business Insider in an email: "We use different words in order to differentiate between affectionate language and common language, so that we can made our loved one feel special.

"Latin and Greek used diminutive forms to express affection 2,000 years ago, just as today's languages do eg: -chen in German."
