The verb lie is often confused with the verb lay, giving rise to incorrect uses such as he is laying on the bed (correct use is he is lying on the bed) or why don’t you lie it on the bed? (correct use is why don’t you lay it on the bed?). See lay1 (usage).
The different verb forms are: (lies, lying; the past tense is lay and the past participle is lain).
