- I mean when I give my girlfriend a silver star as a gift, and I say "sweetheart, this is a tutelary star. It will protect both of us / the two of us". That's what I mean. So, "tutelary star" are not common words? if not, which words are appropriate?
And here I was thinking it was some kind of thing in a video game thing that would give you special powers. I have never seen this word in my life. Could you say it's a good luck charm? But it doesn't matter what words I've seen. If your girlfriend knows the word, then use it.
