'lenticular-bedded' originates from Modern English as a compound of 'lenticular' and 'bedded'. 'lenticular' originates from Latin, specifically the word 'lenticula' (a diminutive of 'lens'), where 'lenticula' meant 'little lens' or 'lens-shaped'; 'bedded' derives from Old English 'bedd' with the adjectival suffix '-ed', where 'bedd' meant 'bed'.

'lenticular' changed from Latin 'lenticula' (diminutive of 'lens') to Medieval/Latinate adjective 'lenticularis' and was borrowed into English as 'lenticular' in post-medieval scientific usage; 'bedded' evolved from Old English 'bedd' to Middle English 'bedded' and into modern English 'bedded' as an adjective meaning 'having beds'.

Initially 'lenticula' meant 'little lens' (a physical lentil- or lens-like object) and 'bedd' meant 'bed'; over time 'lenticular' came to mean 'lens-shaped' in descriptive and scientific contexts and 'bedded' came to describe the arrangement of strata, so the compound now denotes 'having lens-shaped beds'.
