'long' originates from Old English, specifically the word 'langian,' where 'lang' meant 'to grow long or to lengthen.'

'langian' transformed into the Middle English word 'longen,' and eventually became the modern English word 'long.'

Initially, it meant 'to grow long or to lengthen,' but over time it evolved into its current meaning of 'to have a strong desire or yearning for something.'
