I can't reproduce this in Edge Version 91.0.864.64 (Official build) (64-bit).<p>Do you have a Webster add-on, or a bookmark with a keyword of "meaning"?
I noticed this today for the first time.<p>"meaning of [anything]" becomes "Webster's meaning of [anything]" in Chrome and Edge.<p>In Firefox, "meaning of [anything]" stays as "meaning of [anything]".
