Each Sense of a Lexeme can have one or more Glosses to describe the Sense. Initially we only allow them to be in one language. However we want them to be translatable. In the end you will have one Gloss with translations into several languages.
For now we show them all - probably in the order they come in. In the future we will want to be smarter and show initially only the ones in languages the user speaks or do some intelligent sorting.
