I like the word investigate. It can be applied in so many ways. You can investigate the contents of your son’s closet or your daughter’s Facebook page, the contents of a book, or the composition of a compost pile. An inquisitive person needs to investigate interesting stores, the woods behind the farm, and anything around the next corner. While investigating, one becomes an investigator and does an investigation. Investigating the causes of an illness makes doctors and scientists investigators performing investigations. Thank goodness for them.
Of course, there is the police investigation and the investigation by the amateur sleuth, like in my cozy mysteries. The sleuth investigates when she should leave that to the professionals. Examine, explore, inspect, study, consider, probe, scrutinize, reconnoiter, research, look into, and poke around are all synonyms for investigate. It’s a good thing there are words I can use in place of investigate. No one wants to read the same word twenty times in one paragraph like you’ve just done!
