I think word-meaning adds nothing. But maybe I'm not nuanced enough.
If there are questions using word-meaning, and questions using meaning, then the two tags should be merged, and word-meaning made synonym of meaning. That is an operation moderators can do from a single page: the same page used to merge two tags.
These are now synonyms, but they are not merged.
What does that mean, given that they are synonyms? Do we have to request a merge for each of these?
