"Mayday" is a distress signal used in emergency situations, particularly in aviation and maritime contexts. The term originates from the French phrase "m'aider," meaning "help me." It was adopted in the early 20th century as a standardized distress call to quickly convey the need for assistance. People may also colloquially use "Mayday" to express a feeling of being overwhelmed or in need of help in everyday life.
