'clearly-ended' originates from the combination of 'clear' and 'end,' where 'clear' meant 'free from doubt' and 'end' meant 'termination or conclusion.'

'clearly-ended' evolved from the Old English word 'endian,' meaning 'to end,' combined with 'clear,' which has roots in the Latin word 'clarus,' meaning 'bright or distinct.'

Initially, it meant 'to end in a clear manner,' and this meaning has largely remained the same in modern usage.
