Important tip for speaking/writing English more naturally: the

shortcuts

I am——> I’m
You are——> you’re
He/she is——> he’s/she’s
It is——-> it’s
We are—-> we’re
They are—-> they’re
Negative
He is not/ she is not—> he isn’t / she isn’t
(Or you can say “he’s not” or “she’s not)
You are not/we are not/they are not——> you aren’t we aren’t /they aren’t
(Or you can say you’re not / we’re not/ they’re not)

I will—-> I’ll
You will—-> you’ll
He/she will——> he’ll/ she’ll
It will——-> it’ll
We will—- we’ll
They will—-> they’ll
Negative
“Will not”—-> won’t ( this is the same for all grammatical persons)

I would——-> I’d
You would—-> you’d
He/she would —-> he’d/ she’d
It would—— it’d
We would ——> we’d
They would—-> they’d
Negative
Would not——> wouldn’t (this is the same for all grammatical persons)

Negative with past tenses
Did not (used with all grammatical persons)—>didn’t
Was not (used with I, he/she, it)—-> I wasn’t, he/she wasn’t, it wasn’t
Were not (used with you, we, they)—-> you weren’t, we weren’t, they weren’t.

^^^The positive with past tense for these specific words don’t have shortcuts like they do when they’re negative, it’s always “did”, “was”, and “were”. There’s no way you can shorten the words if they’re positive.

All English speakers from every English speaking country use these grammatical shortcuts very commonly. These are just some examples. Also, don’t worry if you don’t use these shortcuts, you will still be understood. In fact, sometimes there are contexts where it’s better to not use the shortcuts. It’s only if you want to sound more like a native speaker. Hope this makes sense/ helps.
