Difference between Lay,Lie,Lie

#Lay_Lie_Lie
lay = put someone or something down

This is a transitive verb, meaning that it’s followed by a direct object (the person or thing affected by the verb).
Here are some examples:
Present tense: I can’t even find someone to lay tiles.

Past simple tense: She laid her hand upon his arm.

Present continuous tense: We’re laying the groundwork for long-term economic growth.

Past perfect tense: The government had laid their cards on the table.

lie (1) = be in a horizontal position on a surface.

This is an intransitive verb, so it’s not used with an object. This is the main grammatical difference between lie and lay.
Here are some examples:
Present tense: The wreck lies in 30 metres of water.

Past simple tense: Last night, I lay on my bed and wept.

Present continuous tense: She’s lying down, but feeling OK now.

Past perfect tense: For more than three years her son had lain in a coma.

lie (2) = deliberately say something that’s not true

This is also an intransitive verb, but hooray, it has a completely different meaning from the other two and so people are less likely to use it incorrectly.
Here are some examples:
Present tense: He lies to everyone in his life, including himself.

Past simple tense: I lied about my age to get the job.

Present continuous tense: You say you like me, but I know you’re lying.

Past perfect tense: They knew that he had lied at the trial.

If you’ve been paying attention, you’ll see that one immediate source of confusion is that lay can be both the infinitive and present tense of the transitive verb lay, meaning ‘put someone/something down’ or the past tense of the intransitive verb lie, meaning ‘be in a horizontal position on a surface’. The evidence on the Oxford English Corpus shows that people often mistakenly use lay when they should be using lie:
