Literary Hub: What Makes A Great Opening Line?

Allegra Hyde writes about opening lines in Literary Hub:

By “clarity,” I mean the ability of a first sentence to give readers an initial hand-hold for place and/or time and/or character and/or plot. Clarity is essential for a first sentence because, at the start of a story or novel—barring whatever information a reader might have encountered on the jacket copy or in reviews—the reader’s mental theater is a void. An unlit stage. A nothingness. Every word in that first sentence is an opportunity to shine a light on what is to come—to give a reader enough information to stabilize them in some degree of who and where and what the story is about.
