I'm working on a book about a girl and a dragon. The dragon is one of the central characters to the story, which is written in third person point-of-view from Sarah's (the girl) perspective. The issue is the dragon cannot speak to humans, so he has to use physical gestures and sounds. I'm working on a list of sounds and their meanings (like when he'd use them), but there are a few sounds in my head that I can't figure out a word for. I don't even know how to describe them! They're softer sounds, like a cat's "rrrrr?" (only from the throat) or a voiceless exhale of air that isn't angry or snotty like a huff (our dogs used to make this sound). This is the list of what I have (please note that this is still a work in progress): Growls (heavy and light): Anger, frustration, warning (getting aggressive), go away, scolding, “no,” disagreement. Purr (comes from the throat): “I love you,” affection, soothing another when they're sad or emotional (not fearful). Rumble (comes from the chest and vibrates the ground): Soothing fearfulness, saying hello/introduction, sad himself. Whine: Pain, very worried Screech: I’m coming (casual, from a distance), where are you, get back or I’ll get aggressive, locating a friend, saying hello long distance to a friend —Usually intermixed with screams and roars during battle to show rage, usually very short. Scream: Extreme pain/surprised pain/pain in battle, frantic where are you (looking for young, etc.), I’m coming (worried/willing to fight if needed) —usually intermixed with screeches and roars during battle to show rage, usually long Roar: Long distance go away, get back (or I'll bite), I’m coming (to kill you/whatever’s hurting you), rage, saying hello long distance to a stranger (to show them his strength and to warn them not to fight him), territorial (this is how strong I am). —Usually long, can be used to substitute screeches and screams in a storm that drowns them out. And these are the two sounds I've figured out I need: "rrrr?" unnamed sound from throat (I guess this is almost sort of a growl, but not quite; it starts low and goes up in pitch): Curiosity (often coupled with a head cock), "how are you," asking something Voiceless exhale (can also be open-mouthed for more exaggeration/add a little volume): Agreement, yes, Any suggestions will be appreciated!
