laid-out

The compound adjective 'laid-out' is a direct product of the phrasal verb 'to lay out', which has been in use since Middle English. The core logic stems from the literal action of laying something flat or arranging items in an open, external space ('out'). From this concrete sense of spatial arrangement for display or planning, the meaning extended metaphorically. One extension describes the designed arrangement of a physical area, such as a town or room. A further, more colloquial extension applies the concept to a person's state, imagining one's energy or vitality as being fully spread out and depleted, leading to the sense of being exhausted.

Structure: laid (past participle of 'lay') + out (adverb/particle) 'laid' originates from the Old English verb 'lecgan' (to place on the ground), from Proto-Germanic lagjaną. In this compound, it functions as the past participle, indicating a completed action of placing. 'out' originates from Old English 'ūt' (adverb), from Proto-Germanic ūt, meaning 'outside' or 'away from the inside'. It functions as an adverbial particle specifying the direction or result of the action.
