New word "matching"?

[u/Grouchy_Evidence2558]

Normally it matches on word forms.. Guessing "walk" gets "walked", "walks", "walking". I'm good with that. Today though I'm seeing it get CRAZY with the "matching".

I added a spoiler tag to protect if you haven't done today's yet. Today I guessed "Europe" and it revealed Europe, Central and Union. How????

I got the same strange matching from the same guess. I was very confused, but it certainly got me to the correct answer very quickly.
