As a detective trying to solve the mystery of the crossword clue ‘Trendy‘, my first step was to brainstorm the words that come to mind when I think of something that is fashionable or popular at the moment. Words that immediately came to mind were ‘popular‘, ‘in demand‘, ‘hip‘, and ‘trendy‘. The word ‘trendy‘ itself contains a hidden clue; the word ‘trend‘ implies that we are looking for something that is currently popular. Secondly, I considered the number of letters in the word ‘trendy‘. It was clear that the answer would be a three-letter word. This meant that I needed to think of a commonly used and small word that could fit in this space. Finally, after considering all these factors, my intuition led me to the answer ‘HOT‘. If something is described as ‘hot‘, it is most likely trendy, popular, in-demand, and currently fashionable. This thought process helped me unlock the mystery of the crossword clue ‘Trendy‘.
