As a detective, I first look closely at the crossword clue ‘Refuses to‘ and think about the different words that can fit in the blanks. I start to think about words or phrases that indicate unwillingness or stubbornness. ‘Won’t‘ comes to mind, as it is a contraction of ‘will not‘ and refers to someone refusing to do something. It also fits perfectly in the blanks of the crossword clue. Additionally, I consider that ‘won’t‘ is a common phrase in everyday language and is often used to express refusal. Putting all these insights together, I confidently fill in the answer ‘WONT‘ and move on to the next clue.
