"Mayday" is an internationally recognized distress signal used in emergencies, particularly in maritime and aviation contexts. It is a call for help, indicating that a vessel or aircraft is in grave danger and requires immediate assistance. The term is derived from the French phrase "m'aider," meaning "help me." When a "Mayday" call is made, it is typically repeated three times to ensure clarity and urgency. This signal alerts nearby vessels, aircraft, and rescue services to the situation, prompting them to respond quickly. Proper use of "Mayday" can be crucial in saving lives during critical emergencies.
