Many times I will know all the characters in a name but one & I'll ask what that one character means. 9 times out of 10 the response is, "That character has no meaning".
While it might be true that the character isn't used on its own, of course it must have meaning otherwise it wouldn't exist.
If someone asked me about a character, I might say, "Oh, in this phrase XX it means something like 'luck' but it isn't ever used alone".
Why does it seem that native speakers aren't willing to answer in that way? Why would a native speaker choose to say that a character has no meaning?
