I spoke with a teacher about an essay I wrote recently. We talked through certain parts which couldn't be described by squiggles and dots in red ink. This helped me, but I'm having difficulty now with identifying the meaning of certain squiggles and dots in red ink.
In "never-ending," my teacher drew a vertical dash through the hyphen, and then made vertical parentheses around the dash (two arcs, each curving from "never" to "ending").
What does this mark mean? I assume it means "remove the hyphen and separate 'never-ending' into two words."
Also, "never-ending" serves as an adjective in this context.
