Google now can show you words they think you’ve searched Google for to get dictionary answers. If you search for [dictionary] or other variations around that, Google will show you “Words you’ve searched” previously for. I don’t think this is super new, at least some have said they’ve seen this for a few months now.
The funny thing is, I did this for myself and I know I didn’t search these terms for dictionary responses – although they may have returned Google definitions at the top:
