3. 'Lay' Versus 'Lie' in the Past Tense
But then everything goes all haywire, because "lay" is the past tense of "lie." It's a nightmare! I tried and tried to come up with a mnemonic for this, but I couldn't do it. Instead, I've made a table that you can print out from the website and tape up over your desk or in your notebook, because you just have to memorize this or look it up every time.
4. How to Conjugate 'Lay' and 'Lie'
