Only solved by process of elimination.
There are so many words that people actually use on a regular basis that contain 5-letters.
I might be over Wordle.
Me, too - thought I had it in 3 and nope...so then I sat and was like "words are no longer possible" - then I thought of one and put it in for 4. And then I googled to see what would have been possible with my remaining letters and my board...and apparently, there was only one word in the English language. So, I felt better it took me a while to find it...
