Once I submitted ADIEU and had the I in place I thought of a few words that could fit and settled on MOIST after thinking it over. I was hesitant on submitting it because of its sexual connotation but I just went with it and it paid off!
Haha damn! Surprisingly I'm fairly certain I'd never used it in any of my previous guesses which in turn made me try it today
3/6, but I almost had it in 2/6 because I thought of the word as a possible guess after my first word ADIEU GRAND SHARD
4/6 here, because if you get the first 4 letters, there are a few to use for the last. This will annoy lot of people.
