lie / lay

and then go lie down in bed.

Lay is to place, lie is to recline. A good trick to remember this is the "a" in lay is also in place, while the "i" in lie is also found in recline. I'm going to lay the book down on the table, and then go lie down in bed.

Usage Discussion of LAY

lay has been used intransitively in the sense of “lie” since the 14th century. The practice was unremarked until around 1770; attempts to correct it have been a fixture of schoolbooks ever since. Generations of teachers and critics have succeeded in taming most literary and learned writing, but intransitive lay persists in familiar speech and is a bit more common in general prose than one might suspect. Much of the problem lies in the confusing similarity of the principal parts of the two words. Another influence may be a folk belief that lie is for people and lay is for things. Some commentators are ready to abandon the distinction, suggesting that lay is on the rise socially. But if it does rise to respectability, it is sure to do so slowly: many people have invested effort in learning to keep lie and lay distinct. Remember that even though many people do use lay for lie, others will judge you unfavorably if you do.

Lots of words that don't say anything. I'll stick with the way was taught, thanks.

Lay, lady, lay, lay across my big brass bed
Lay, lady, lay, lay across my big brass bed
Whatever colors you have in your mind
I’ll show them to you and you’ll see them shine

Really JT? using pop song lyrics as a guide to grammar?

It ain’t no use in turnin’ on your light, babe
That light I never knowed
An’ it ain’t no use in turnin’ on your light, babe
I’m on the dark side of the road
Still I wish there was somethin’ you would do or say
To try and make me change my mind and stay
We never did too much talkin’ anyway
So don’t think twice, it’s all right

That is not a "natural fashion" at all. Do you think a normal person would speak these words to a real woman (without singing)? No, it is song lyrics. It is poetry. It is not natural speech.

All I am saying is that using Dylan as an example of good grammar is bogus (although humorously so).

I won't tell you that I love you
Kiss or hug you
Cause I'm bluffin' with my muffin
I'm not lying, I'm just stunnin' with my love-glue-gunnin'
Just like a chick in the casino
Take your bank before I pay you out
I promise this
Check this hand cause I'm marvelous
