Common Wordle starting words: crane, slane, raise, audio, slant, plant, crane. We need 5-letter. I'd pick [crane] common. But maybe better [slane] has distinct common letters S L A N E. [crane] C R A N E also distinct common. [slane] covers vowels A E, common consonants S L N. [raise] R A I S E. [audio] all vowels. [plant] P L A N T. Since no feedback, any.

R is in the word. From guess 2, R was in position 3 and got Y, so R is not in position 3. From guess 3, R was in position 2 and got Y, so R is not in position 2. Position 1 is A, position 4 is E. So R must be in position 5.\n\nNow we have:\n- Position 1: A\n- Position 4: E\n- Position 5: R\n\nWe need to fill positions 2 and 3.\n\nLetters we know are NOT in the word: S, L, N, C, D, T\n\nLetters we know ARE in the word: A, E, R\n\nWe need two more letters for positions 2 and 3.\n\nLet me think about common 5-letter words matching A _ _ E R:\n- ACHER?

No\n- AVER? No\n\nWait, I should also consider that maybe I'm wrong about R being in position 5. Let me re-examine.\n\nFrom guess 2: C A R E D \u2192 X Y Y G X\n- R is in position 3, feedback Y means R is in the word but not in position 3.\n\nFrom guess 3: A R E T E \u2192 G Y Y X X\n- R is in position 2, feedback Y means R is in the word but not in position 2.\n\nSo R is not in position 2 or 3. Position 1 is A, position 4 is E. So R must be in position 5. That seems correct.\n\nSo the pattern is A _ _ E R.\n\nLet me think of common words:\n- ACHER (not really a common word)\n- AIDER (D excluded)\n- AIMER (I, M)\n- AMBER (M, B)\n- ANGER (N excluded)\n- ASHER (S excluded)\n- ATHER (T excluded)\n- AURER (not a word)\n- AVER?

A _ _ E R:\n- ACHER\n- AIDER\n- AIMER\n- AMBER\n- ANGER\n- APER\n- ASHER\n- ATHER\n\nHmm, what about:\n- ACHER (a person who chafes?)\n- AIDER (one who aids) - D is excluded\n- AIMER (one who aims)\n- AMBER (a fossilized resin)\n- ANGER (emotion) - N is excluded\n- ASHER (one who ashes) - S is excluded\n- ATHER (a type of fish?) - T is excluded\n\nWait, I should also think about less common words.

Let me check:\n- A: position 1 \u2713\n- M: position 2\n- B: position 3\n- E: position 4 \u2713\n- R: position 5 \u2713\n\nNone of M or B have been ruled out.
