I have a reasonable vocabulary but I just got the word “copra”. I did get it on the sixth try but only after guessing cobra and realizing there were no letters left that produced words I knew. According to Wikipedia “Copra is the dried coconut kernels of which coconut oil is expelled.” It might be a blind spot in my vocabulary but I haven’t had this happen with wordle. The accessible word list could be considered another genius element of its design.
