"My hat is there."

Translation: Il mio cappello è là.

[ceceg]

Both lì and là are given as meaning "there." Is there a rule for knowing which to use where?

[Aratal]

As a general rule, lì refers to something that's close to you, and là refers to something that's farther away. Kind of like "there" and "over there."

Right on the nail.

[f.formica]

Technically, lì indicates a more specific area than là; but nowadays they're used interchangeably.

[phoebepeebles]

But apparently not by Duolingo.

[lea.kharsh]

At times il or la is used before mio or mia and at other times it's incorrect to use il or la. Is there a rule?

Thanks for the link, I was unsure about that as well.

[fonf123]

why can't i say "mio cappello è là", i'm confused about when you can use or omit the article.

[juanpablob217877]

You omit the artticle when is a family member

[murathem]

I thought the article wasn't necessary when speaking about personal clothing items?

[xyphax]

The article is required. You might have heard this rule:

Omission of possessive adjectives : In general, possessives are not used with parts ot the body or clothing of the subject when they are the object of the action taken by the subject.

that is from this link.

[Caterinabella]

It's best to be grammatically correct, but if one were conversing in Italian it would still be understood what is being said even if the article is omitted in conversation.
