Can you explain this sentence to me? "In my going out altogether, like a candle" .
"...she felt a little nervous about this; 'for it might end, you know,' said Alice to herself, 'IN MY GOING OUT ALTOGETHER, LIKE A CANDLE.

This is a passage from the book ALICE IN WONDERLAND which I'm currently reading. I came across this sentence "in my going out altogether, like a candle". (She had just drunk the liquid from the bottle labelled "DRINK ME", after drinking it, she waited a few minutes to see if she would shrink any further.)

Answer

In English, we use the phrase "to go out" idiomatically to say that something is extinguished, like a candle or a light. Thus, Alice is nervous that her life might end. It would "go out" like a candle.
