about 's

' is called an apostrophe. It is used with s to indicate some contraction or the possessive.

It's been hot all day. = It has been hot all day.
She's a fast runner. = She is a fast runner.
This is Peter's car. [The car belongs to Peter.]

Farassoo Is 's always pronounced in speaking?

Yes, it is. Do you have a particular example in mind?

I was watching a movie. I think when someone is speaking they don't pronounce some of 'Ss and Ss(I mean the ending letter in verbs and other words).?!

Which movie? Do you have a link to a scene where you suspect they do that?

I think most English speakers do pronounce the ending -s or -'s. There are some dialects where endings are dropped or slurred.

Thank you AlpheccaStars and teechr
The movie is Mary and Max
Max says: Do worm go to heaven? I found a subtitle and it says: do worms go to heaven...?

Thank you. The movie I think it's Australian. I found two examples but I can't find the other one now.

Farassoodo worms go to heaven

That's a different s; there's no apostrophe there. It's used in that sentence for the plural "worms."

In any case, Australians do pronounce it.

Thank you. I didn't find that one with 's

If you listen carefully, you'll notice that he actually says "worms" not "worm."

Sorry. I can't hear that. Maybe I should use a headphone. Thank you so much
