ASK A QUESTION How do you say to lay down
ex. to lay down on a bed
Do you mean "to lie down" as in a person lying down on a bed? That would be "acostarse". Example: "Me acuesto" - I lie down.
Or "to lay something down on a bed" is "poner" or "colocar". Example: "Pongo mis libros en la cama." - I lay my books down on the bed.
