4.179

懶惰（上亦作嬾同勒坦反下又作墯同徒臥反考聲云不勤也說文不敬也並從心賴隋聲也）。

懶惰: The upper [character is] also written as 嬾, identical to the fanqie le + tan. The lower [character is] also written as 墯, identical to the fanqie tu + wo. The Kaosheng states: 'Not diligent.' The Shuowen jiezi states: 'Not reverent.' Both are formed with the heart radical (心), with lai (賴) and sui (隋) providing the phonetic sounds.
