"Etc." is an abbreviation of the Latin phrase "et cetera," meaning "and other things" or "and so on." It is used in writing to indicate that a list continues beyond what is mentioned. In letters, it can suggest that additional similar items or ideas exist without needing to specify each one. It helps to keep communication concise while implying completeness.
