MAY-day/mˈeɪdeɪ/

The person on the sinking boat sends a mayday by radio.

A woman aboard a sinking small boat urgently transmits through a marine radio microphone, making the connection between immediate danger and a radio distress call visible.
Etymology

The French appeal “help me!” supplied the sound of this distress call. A spoken signal was needed because the S in telegraphic SOS was difficult to hear over early radio.
