What Causes the Confusion?
"There's" and "theirs" sound somewhat the same, but they have different meanings and spelling.
Theirs: Possessive Pronoun
'Theirs' is the third-person plural possessive pronoun which is used to refer to something or someone belonging to or associated with others.
I need a car because my parents can't give me
We can use 'theirs' instead of 'his or hers' to show that something belongs to a person without mentioning the gender of those people.
I've read every author's point of view on that article, I don't agree with
There's: Short Form
'There's' is the short form (or contracted form) of:
- There is
- There has
There's = There Was?
Although you might hear someone use the contracted form of 'was' in spoken language, but you should know that it is not grammatically correct. Unless there are obvious signs that the sentence is in the past tense, avoid using 's' as a contracted form of 'was'.
