Any from your language/s. It doesn't matter whether they're used widely or even by only one person that you know of. I'm mainly interested in all the places they can come from: pet, hen, chicken, duck, lamb (animals, mainly small ones or young animals, including 'baby', 'little one', maybe to show that the person's precious, or yours to protect?); comrade (military, fighting together and on the same side for a time to come); brother, darling, dear, love, lovely, and so on... the ones I know in English include lots that signify loving someone fully, or some attribute to the person in question, such as beautiful or sweet. People are often called smart, brave etc (a more direct appeal to their personality or achievements), but generally not as a name, and if so usually as a teasing one. I'm just wondering where they come from and if there are any missed in British English that appear in other places.
