As a detective tasked with solving the mystery of the crossword clue ‘Make broader’, my initial thought was to consider words that are synonymous with broader such as wider, larger, or bigger. I quickly determined that ‘Make larger’ would not fit within the given space, and ‘Make bigger’ was too ambiguous as it could refer to physical size or quantity. However, ‘Make broader’ implies expanding something in width, and ‘Widen’ quickly came to mind as the most fitting answer. This insight was further solidified by the fact that ‘Widen’ is a commonly used verb in everyday language, accurately fitting the definition of the crossword clue. As a helpful assistant, I hope this explanation will guide you in your future crossword solving endeavors.
