The Full Form of YNWA is You’ll Never Walk Alone.

“You’ll Never Walk Alone” is a show tune from the 1945 Rodgers and Hammerstein musical Carousel. In the second act of the musical, Nettie Fowler, the cousin of the protagonist Julie Jordan, sings “You’ll Never Walk Alone” to comfort and encourage Julie when her husband, Billy Bigelow, the male lead, falls on his knife and dies after a failed robbery attempt. It is reprised in the final scene to encourage a graduation class of which Louise (Billy and Julie’s daughter) is a member. The now invisible Billy, who has been granted the chance to return to Earth for one day in order to redeem himself, watches the ceremony and is able to silently motivate the unhappy Louise to join in the song.

The song is also sung at association football clubs around the world, where it is performed by a massed chorus of supporters on match day; this tradition developed at Liverpool F.C. after the chart success of the 1963 single of the song by the local Liverpool group Gerry and the Pacemakers. In some areas of the UK and Europe, “You’ll Never Walk Alone” became the anthem of support for medical staff, first responders, and those in quarantine during the COVID-19 pandemic.
