You are a language wizard who likes to guess words by using the given rules.

Welcome to Wordle! You have six attempts to guess the target word, a valid English word of five lowercase letters (a-z). Please use the tags "guess:" and "explanation:" to provide a concise explanation for each guess.

For instance, if your guess is "apple", your response should be
guess: apple
 explanation: this is a common five-letter English word, and I am starting my guess with this word.

After each guess, your answer will be validated, and you will receive feedback indicating which letters are correct (green), which letters are correct but in the wrong position (yellow), and which letters are incorrect (red). This feedback can be useful in determining which letters to include or exclude in your next guess.

For example, the feedback for "apple" might be:
guess_feedback: a<yellow> p<yellow> p<green> l<yellow> e<red>

The explanation should contain details about how the guess_feedback is used to arrive at a new guess.

Let's begin with your first guess.

guess: crane
explanation: This is a common five-letter English word that includes a good mix of vowels and consonants, which can help to narrow down the possible letters in the target word.

guess: berry
explanation: Based on the feedback, the letter 'r' is in the word but not in the second position, and 'e' is in the word but not in the fifth position. I am guessing "berry" to test the placement of 'r' and 'e' and to introduce new letters.

guess:rebel
explanation:The feedback indicates that 'e' and 'r' are in the word and in the correct positions as the second and third letters, respectively. I am now trying "rebel" to keep 'e' and 'r' in their places and to introduce new letters for the first, fourth, and fifth positions.

user
guess:serve
explanation:The letter 'r' is in the word but not in the third position, and 'e' is confirmed to be in the second position. I am now trying "serve" to test the placement of 'r' in the first position and to introduce new letters 's' and 'v' while keeping the correct 'e' in place.

guess_feedback: s<green> e<green> r<green> v<red> e<red>
user
guess:serif
explanation:The feedback confirms that 's', 'e', and 'r' are in the correct positions as the first three letters of the word. Since 'v' and the second 'e' are incorrect, I am guessing "serif" to fill in the last two letters, which have not been guessed yet.

user
guess:serum
explanation:The first three letters 's', 'e', and 'r' are correct. The letters 'i' and 'f' have been ruled out for the fourth and fifth positions. I am now guessing "serum" to try the letter 'u' in the fourth position and 'm' in the fifth, which have not been used in previous guesses.
