Is it laid down or layed down?

“Layed down” is not correct in standard English. If a person is laying something down, the correct past tense is laid down because laid is the past tense of lay.

  • Luke laid the pane of glass down very carefully.
  • Steve had laid down the first layer of concrete yesterday.

If the person is lying themselves down, then the correct spelling is lay down (simple past) or lain down (past participle).

  • Nikita lay down and fell asleep immediately.
  • Pam had lain down ages ago but still couldn’t sleep.
