As a detective, I first focused on the phrase “more or less,” which indicates an approximate amount or date. Next, my attention was drawn to the phrase “in time,” implying a reference to a specific point in history. Putting these two ideas together, I considered words that denote an approximate time or date, such as “around” or “about.” After a few moments, the word “circa” came to mind, which means “approximately” in Latin. This seemed to fit perfectly with the given clues, so I confidently filled in the answer in the crossword puzzle. In conclusion, the combination of deductive reasoning and language knowledge ultimately led me to the answer of “circa” for the crossword clue “More or less, in time“.
