omissible
Can be dropped
Omissible describes something that can be left out without significant loss.
In grammar, an omissible element is optional: The word "that" is often omissible in sentences like "I think [that] you're right".
More broadly, anything dispensable or nonessential qualifies: The third chapter felt omissible.
