What is the difference between "I am finished" and "I have finished"?
For example, when finishing a task, should I say "I have finished" or "I am finished". Is there a difference in meaning?
Depending on context they could have the same or slightly different meanings
I have finished
would be said after completing a task either very recently or some time in the recent past
I am finished
would be said after very recently completing a task.
It can also have the meaning of hopelessness as a person faces impending doom
I've lost everything, I'm finished.
or drawing a dramatic end to a relationship
She said she was finished with her boyfriend.
You could say either one, but things get more complicated when you elaborate and mention what you've finished:
I have finished this task.
I am finished with this task.
Both are grammatically correct.
I am finished
The speaker is in the state of being finished with a task.
I have finished
This describes the completion of the task in the very recent past. (present perfect tense)
Grammatically, both are correct, but they are linguistically different.
The first sentence does, in fact describe the speaker as in the state or condition of being finished, specifically with the task of washing the dishes. This construction is the more passive of the two.
The second version describes more accurately the completion of the task as the point of reference for the listener.
To put it another way, the first sentence commands the listener to wait until the speaker is in the condition of being finished, the second says to wait until the action is completed.
The example I'm using is the following:
'Wait until I am finished washing the dishes' vs. 'Wait until I have finished washing the dishes'
I am finished is generally used to describe a situation where I am done and want to put an end(or there is no hope for me for that action or thing or person or anything like that.) to life or any action like I am finished with my life. or I am finished with you. while I have finished is used to say that I have completed an action like I have finished that book.
Here is an example... I am finished with the classes means I do not want to attend the classes anymore due to the teacher or I don't understand that subject.
I have finished the classes means there is a confirmation that I have completed the classes.
"I am finished." Here 'finished' is an adjective. "I have finished." Here 'finished' is the past participle form of the verb 'finish'.
Former one explains the state of being finished. It talks about the subject "I". It usually comes with a preposition like "With".
E.g., I am finished with homework.
Note: "I am finished" (without object) means you're fed up with your life, and you don't have a reason to live your life.
Later one is a sentence in present perfect tense. It may take an object as a complement to the sentence.
E.g., I have finished homework.
Note: Here there is no preposition before the object.
You should probably not say "I am finished" in most situations as this implies that your life is at an end. It is the "I" that is finished - i.e. close to death or some sort of catastrophic failure.
