The phrasal verb "cover for" is predominantly used in informal contexts, although it does occasionally appear in more formal communications, particularly in professional settings. It generally refers to the act of taking responsibility or performing duties on behalf of another person, often because that person is absent or needs to attend to something else. For instance, an employee might "cover for" a colleague who is on leave or handling an emergency. Beyond workplaces, "cover for" is also commonly used in everyday situations where someone might conceal or excuse another's actions, perhaps to avoid getting them into trouble. Although it can be used in formal writing, it typically maintains a conversational tone, suggesting circumstances where people rely on one another's assistance or defense.
