Writers and speakers frequently confuse the various forms of lie (meaning “to recline or rest on a surface”) and lay (meaning “to put or place something”). Lie is an intransitive verb; it does not take a direct object: The tax forms lie on the table. The verb lay is transitive; it takes a direct object: Please lay the tax forms on the table. (See B2-b.)
In addition to confusing the meaning of lie and lay, writers and speakers are often unfamiliar with the Standard English forms of these verbs.
