Question about 's and related
If I'm saying: My point is blablabla, can I say it like that: My point's blablabla? Will it be correct?
I'm not sure, but I have a feeling that I can only abbreviate when using pronouns, is that right or am I imagining rules? haha
PS: Nothing to do with the possessive pronoun, only making it clear
You can use 's with nouns and pronouns both. It's worth noting that the 's can come from "is" or "has". Ex: Carolyn's leaving soon, but Harold's already left. = Carolyn is leaving soon, but Harold has already left.
Yeah, I knew about the "has".
So I was just imagining the rule lol
It would be incorrect in formal English, but abbreviating "is" with an apostrophe + S is very common in casual English.
"That song's annoying."
"The cat's acting crazy today."
"The television's broken."
All of these are examples you would be very unlikely to see in print (except maybe in a novel), and they are all technically incorrect, but all things a native English speaker would say in an informal setting.
The example you use, "my point is" would very rarely be abbreviated, but that has to do with the fact that in that particular example, an English speaker would naturally want to emphasize the word "point". The rhythm of the sentence would go, "My point is, we've talked about this be-fore."
A lot of what makes English sound natural has to do with where the stress is placed. If you're interested in learning more about that, there's a TEDx talk about it here: https://www.youtube.com/watch?v=NcX2AwH3cG8
Contractions aren't actually incorrect, they're just informal. You would not use them in formal writing (term paper, newspaper article, job application letter, etc.) unless you're quoting someone who used them.
I believe that "my point's blablabla" is okay in casual conversation. It does not have to be a pronoun such as he's (he is) or it's (it is).
In speech, we (many English speakers) do this all the time. "How's your dog?" "My dog's fine!"
However, if someone asked, "Are you sure that your dog is okay?" You might say "Yes, my dog is fine" to state it more emphatically. So, I agree that "my point is..." would often be said to emphasize it.
Also, an author might be more likely to spell out "my point is" in certain types of formal writing.
