I'm going through my story and trying to fix up the proper use of the verbs (to) lay and (to) lie. I was wondering if I could get some help on the proper use of these words. I understand their meanings (mostly) but I'm having trouble placing them in a few particular ways. Question 1: about describing an object that is on the ground or in a position in space. Is the use of the word 'lay' correct in each of these sentences? 'The fabric was so thin that he could see vaguely what lay behind it.' 'He walked towards the forest that lay behind the house.' 'He awoke only to find the place next to him now lay empty.' Question 2: to lie down. Is the word 'lie' used correctly in the following sentences? '"Let's lie down."' 'She followed his lead to lie down on their sides.' 'He didn't want to lie down but knew his next chance for rest would not come again for some time.' Question 3: The correct word to use to describe the placement of an emotion. Are the words 'lie' and 'laid' used correct here? '"If the raiders come, our only hope lies in hiding in the mountains."' 'He looked into her face and could see no sympathy laid behind her cold blue eyes.' Question 4. Is this correct? 'He laid his eyes upon them.' Thanks for any help. I get when to use these verbs in like 9/10 cases but some of them are a bit more tricky than other.
