‘I’m’ is the contraction of ‘I am’. While ‘am’ is a primary auxiliary verb ‘to be’ like: is, are, was, were, am, be, being, and been.
These auxiliary verbs could be used as helping verbs e.g.
- I am eating
- she is reading
They are also used as linking verbs e.g. I am a teacher
The difference between I’m and am is: I’m in the first person singular pronoun I and auxiliary verb am while ‘am’ is just an auxiliary verb that can’t start a sentence. Hence, it’s wrong to write: Am with you my Yori Yori instead write I’m with you my Yori Yori.
I am is used to make a statement, like “I am a teacher”, or “I am a member of the book club”.A
Am I is usually used for:
1. Questioning. “Am I supposed to be here tomorrow?”
2. Challenging (expressing disbelief) a statement. “You are very beautiful.” “Am I?”
3. Rhetoric sentence. “Wow, I am a good mentor, am I now?”
