What does I was wondering, this sentence grammatically correct? "I just wanna lay in my bed"
Is it wrong this sentence? "I just wanna lie on my bed"
I want to know what's the difference between lay and lie mean?

See a translation

Native speakers always make this mistake so dont worry too much about it😂 I will try to explain it simply.

Lay - to place something down
Lie - to be flat on a surface

Lay requires a direct object. You can’t say “lay there” it needs an object- “lay it there” is correct because it has an object (it).

There is no object with lie so you can say “lie down”

The main thing that is confusing is the past tense forms.

Past tense of lie and lay:
Lie - Lay (eg “I lay on the bed”)
Lay - laid

So “I just wanna lay in bed” is actually grammatically incorrect but almost every native speaker makes these mistakes so its absolutely fine but it’s good to know, especially when writing formally.

“Lie on my bed” is correct by the way.
