I am sure somebody has said this already and it does irritate when people get it wrong, but I just sigh inwardly and let it go
However in English English, “to lay”:is a transitive verb ie.takes an object.
Hens lay eggs, I lay down my weary burden , I lay down the law, but also a reflexive verb as in
“ now I lay me down to sleep,
I pray the Lord my soul to keep.”
It’s past tense is “laid” as in “my hens laid six eggs yesterday”
“To lie” is an intransitive verb, cannot have an object and its past tense is “lay” - I lie on the bed, the books lie on he floor, at the battle of Trafalgae many wounded sailors lay on the deck” etc.
And course to indicate geographical position, e,g,London lies South of Birmingham etc.
