Assuming that any string of letters is allowed and the word to guess is ABCDE what will happen if ..

The proposed solution must be an English word, although English usage includes words from other languages, like PIZZA. You can’t enter a string of random letters.

However, you can come up with 3 words for your first 3 guesses that include the most commonly used letters without repetition, thus eliminating 15 letters out of 26. Some people use that systematic approach.

You need to enter a valid word. A string of the same or random letters will be rejected.

You will get 1 green & 4 grays. Because testers only 1 e in the answer

The Guest Answer is also the approach I use and also use up all the vowels. I have two sets of my first three words, one that I use on odd numbered days and one for even numbered days. They are "ORATE", "INCUS", and "LYMPH"; or "SERAI", "DONUT", and "LYMPH". For variety I can substitute "ARISE", "RAISE", or "REAIS" for "SERAI". This technique allowed me remain undefeated and solve almost a thousand games.
