With English being my second language, it is difficult to remember the correct usage of "lie" and "lay" - especially in the past tense :-)
I know that a "lie" is a fib and that a chicken "lays" eggs, but then we get to lying down it gets murky for me. It is easier to use lying down in a sentence, but when it gets to past tense, then what do you say?
E.g. "I lay down on the couch and then my dog jumped on too" - is this correct?
Will appreciate a comprehensive answer with adequate examples of everyday usage!
