Why there are 2 verbs in the sentence, Jim shoved open the door.
shove

To shove is also to slide something along a surface by moving or pushing it:
[ T ] She got into her coat and shoved her hands deep into her pockets.
[ M ] Jim shoved open the door (= pushed the door to open it), and invited his visitor in.

There is a sentence , Jim shoved open the door. I want to ask, shoved is a verb, open is a verb too. It seems to be odd. Why there are 2 verbs in the sentence.
And i don't know what does the signal "[M]" mean.

Answer

"Open" can be a verb, "to open," but it can also be an adjective. To illustrate:

The door is red. It is a red door. You paint the door white. Now it is a white door. "Red" and "white" are adjectives here.

The door is closed. It is a closed door. You push the door open. Now it is an open door. "Closed" and "open" are adjectives here.

Answer

In the sentence, the only verb is “shoved”. “Open” is not a verb, but an adjective, used as a sort of adverbial complement. Jim shoved the door so that it would be open as a result. Other complements we could use with “shove” are: closed, over, down, aside, etc. This is similar to such expressions as verbs: to run / walk / fly 
complement: away / back / up / down / etc.

Answer

Open is an adjective.

He pushed the door open.  <=  open is a resultative adjective which describes the door after being pushed.
He painted the door blue.

Answer

In the sentence "Jim shoved open the door, and invited his visitor in" the words "shoved" and "invited" are verbs.

As far as the phrase "shoved open" there is some discussion as to whether the word "open" would be considered and adjective or an adverb. People argue about this frequently, but the point is that the word "open" is being used to describe the state that the door is in.

In this sentence, Jim is not opening a door, he is shoving a door into an open position.

I hope this helps!

Answer

'Open' is an adjective in the sentence, not a verb. The meaning would be the same if the sentence was written, Jim shoved the door open. I can see how the sentence would be confusing, I hope this explanation helps.
