GRE pro tips:
Serendipitous is the adjective form of serendipity: an instance or knack for having lucky or fortunate encounters or discoveries – or, in other words, being lucky by being in the right place at the right time. A serendipitous event is unplanned and happens by accident, so it’s typically when you least expect it. And the outcome of something serendipitous is both unforeseen and fortunate.
Many scientific discoveries, for instance, occur quite serendipitously! Take the example of biologist Alexander Fleming’s serendipitous discovery of penicillin: When growing bacterial cultures, Fleming hurriedly left for a trip and accidentally left one Petri dish open. When he returned, a mold had formed and had killed off all surrounding bacteria in the culture. This was a serendipity that led him to identify and isolate the powerful antibiotic (from the mold).
