The term "when" refers to a specific point in time or a period during which an event occurs. It helps to establish the timing of actions, decisions, or occurrences, allowing for better understanding and organization of events. For example, asking "When is your birthday?" seeks to identify the date of a person's birth. In everyday language, "when" can also be used to inquire about future events or conditions. For instance, "When will the meeting start?" indicates a need for information about the timing of the meeting. This word is essential for effective communication and planning in various contexts, such as school, work, or social gatherings.
