Confusing Words

lay vs lie

Lay' and 'lie' are easily confused because they are similar in form and relate to the same idea of resting or placing something flat — and the past tense of 'lie' is 'lay', which adds to the confusion.

  • lay — lay' is a transitive verb — it always takes an object (something is laid down) — for example, ‘She carefully lay the fragile document on the table.’ In the present tense: ‘She lays her books out each morning.’
  • lie — lie' is an intransitive verb — it does not take an object (someone or something rests on its own) — for example, ‘The injured student had to lie down in the sick bay.’

Memory rule: A clear way to keep them apart: if you can put something down somewhere, use lay (you are placing an object); if someone or something is resting on their own without being placed, use lie.
