So, I'm looking for terms one might use as nicknames in two ranges. For one character, I'm looking for names that imply smallness and have connections to plants. English equivalents would be "Sprout" or "Seedling". For the other character, I want names that are a bit derogatory, implying youth and ownership primarily. English equivalents could be "pet", "whelp", and "puppy". But I'd also like one positive one, similar to "love" or "my love".
Anyone who has suggestions, I'd love to hear them. I appreciate all help. Thanks.
