A green indication for the left word
My first conjecture yielded a green indication for the left word and, more significantly, the letter 'O,' which ultimately serves as the primary vowel in both words.
Obese eliminated all the dordle vowels in the correct word and provided me with a 'S' on the left. After much contemplation, I deduced my third word; nevertheless, the pool of five-letter words beginning with 'O' and including 'E' in the center is limited, leading me to confidently conclude that 'omega' was the correct choice.
After some deliberation with the letters, I ultimately deduced that use a double 'O' in conjunction with 'bosom' was a viable option. Fortunately, I recognized the need of using a 'S' and thereby circumvented terms such as broom.
