Most named dragons have their names mean something in their language, but shouts are the things that use 3 dragon words put together, they can be used with one or two but more words = better
Well, I'll go with three words as part of the name to match the other dragons I know of in Skyrim.
Also, it has been a while since I played Skyrim, so I might end up making a few mistakes.
Anyway, I already kind of have a character for Skyrim, considering that's how I ended up making Izviing.
Gender & Race: Male Dovah.
Role: Pretty much just working to protect his species.
Strengthes & Weaknesses: He's a frost dragon, so he's resistant to frost, but weak to fire.
Personality: Quite aggressive towards humanoid species, but might let them talk first before he decides to kill them. He specifically hates elves more than anything.
Breath Weapon & Shouts:
Unrelenting Force, Frost Breath,
(And if Frost Breath isn't being considered a shout for dragons, then also
Marked For Death.)
EDIT: Because of Unrelenting Force no longer being required, Iiznahviing now has Marked For Death, Become Ethereal, and Ice Form.
