- The confusion between lie low and lay low stems from the fact that the past tense of to lie (intransitive verb) is lay; whereas the past tense of to lay (transitive verb) is laid. Also, in this case lie low is an idiom so both words must be used together; this is consistent with many other idioms, such as 'hurry up,' for example.
