Etymology
This word came into English from Middle English lither, lyther (“deceitful; evil; false; treacherous; sinful, wicked; leading to cruelty, injustice, or wickedness, perverted; of a country: filled with wicked people; cruel, fierce; dangerous, deadly; frightening; grievous, painful; harmful, injurious; miserable, paltry, poor, worthless; feeble, sluggish; cowardly”) [and other forms], which developed from Old English lȳþre (“bad, wicked; base, mean, wretched; corrupt”) [and other forms], itself from Proto-Germanic *lūþrijaz (“bad; dissolute; neglected; useless”), going back to Proto-Indo-European *(s)lew- (“limp, slack”). Sense 1.2 (“flexible, supple; agile, lithe”) was shaped by the influence of lithe. It is a cognate of Dutch lodder (“wanton person”) and loddering (“drowsy; trifling; wanton”), German liederlich (“dissolute”), lotterig (“slovenly”) and lüderlich (“slovenly”), and Old English loþrung (“delusion, rubbish, nonsense”) and loddere (“beggar”).
