Can anyone explain me when to use ly at the end of words

Dni483 would it be wrong if it's she was widely open or the the is widely open ?

the what?

The door is widely open

I have heard in a movie a phrase like she was wide open , would it be wrong if it's she was widely open or the door is widely open ?

Both "wide" and "widely" are adverbs. "wide" is also an adjective.

With words like the underlined ones, we use "wide" as the adverb.

"widely" is used in sentences like the following. 'He was widely cr

Shall I consider "the door was widely open" as wrong grammar?

Dni483 Shall I consider "The door was widely open." as wrong grammar? I wouldn't say that sentence; it's not a natural sentence. "wide" is natural there.

A person can't be wide, or widely, open because you can't put something into her/him. Saying that a person is wide open tends to refer to an open mind or an open attitude.
'The door is open widely', is more proper than 'the door is widely open'. However, 'the door is wide open' or 'the door is open wide' are both correct.

I'm really confused using adverbs

As far as I know adverbs usually describe how, where and when

Am I right so ther

There are two adverbs "wide" and "widely" with different uses.

Wide (adverb)
- At a great distance
- Spaced or placed to the side of something by a large distance
- To the fullest extent (as fully as possible)
Examples:
We searched far and wide…
The biscuits were placed wide apart for baking...
His mouth was wide open.

Windsor13'The door is open widely', is more proper than 'the door is widely open'.

Neither is correct.

What's the correct way of saying it then ?
