To make a false statement deliberately with intent to deceive. Can also mean to be in or assume a horizontal or resting position.
From Old English 'lyge' (falsehood) and 'licgan' (to recline), representing two distinct Germanic roots that merged in English. The 'falsehood' meaning comes from Proto-Germanic 'lugiz', while the 'recline' meaning comes from Proto-Germanic 'ligjaną'.
English speakers constantly navigate the confusion between 'lie' (recline) and 'lay' (place something down), but historically these were completely separate words that happened to sound similar. The past tense of 'lie down' is 'lay', which is also the present tense of 'lay something down' - a linguistic coincidence that torments writers everywhere.
