Grammar: Deduction (lemme) vs. contractions (I've)

Deduction vs. contractions  (I've, apostrophe) 

https://www.coursera.org/learn/media/lecture/HDVMy/language-focus-reductions

                                                   got to                   gotta

One way to do this is by leaving out some of the middle sounds of a phrase, give me  to gimme, common reductions that leave out some middle sounds include lemme, let me, want to, want to, and gonna, going to

Another way to make reductions is by leaving out one of the N sounds of a phrase. are formed by leaving out the V sound in have. could have, should have, would have, musta, and mighta.

Two more common reductions are formed by leaving out a sound at the end of a phrase, kind of and lotta. They are formed from the phrases kind of and a lot of. So you could say, I'm kind of hungry or I'm not, I ate lotta chips earlier.

They are very similar to other words like can't or she's or I've. These words are contractions. A contraction is a word formed by combining other words and leaving out some letters. The missing letters are replaced with an apostrophe, which is a small mark at the top of the line.
