lust: [OE] Lust is a Germanic word; it goes back to a prehistoric Germanic *lust-, which as well as English lust had produced German lust (now used for ‘pleasure’ rather than ‘desire’). Swedish lust ‘inclination, pleasure, desire’ was borrowed from Low German. From the same Germanic ancestor came the now archaic verb list ‘desire’, source of listless. And it is possible that lascivious [15], acquired from late Latin lascīviōsus, may ultimately be related.

lust (n.)youdaoicibaDictYouDict
Old English lust "desire, appetite, pleasure; sensuous appetite," from Proto-Germanic *lustuz (cognates: Old Saxon, Old Frisian, Dutch, German lust, Old Norse lyst, Gothic lustus "pleasure, desire, lust"), from PIE *las- "to be eager, wanton, or unruly" (cognates: Latin lascivus "wanton, playful, lustful;" see lascivious).

In Middle English, "any source of pleasure or delight," also "an appetite," also "a liking for a person," also "fertility" (of soil). Sense of "sinful sexual desire, degrading animal passion" (now the main meaning) developed in late Old English from the word's use in Bible translations (such as lusts of the flesh to render Latin concupiscentia carnis [I John ii:16]); the cognate words in other Germanic languages tend still to mean simply "pleasure."
