Always Stays the Same
When 'duro' describes how an action is done (like in 'trabajar duro'), it's an adverb. This means it NEVER changes. It's always 'duro', never 'dura' or 'duros'.
Making it Match
Mistake: “Mi hermana trabaja dura.”
Correction: Say 'Mi hermana trabaja duro.' Because 'duro' here describes *how* she works, not her as a person, it doesn't change.
