why is it meus?
meus, since an adjective, matches with liber in grammatical case, gender, and number (nominative, masculine, singular).
Because liber is masculine. :)
Anybody clear on the difference between libro, librum and liber? Would really help to know that - thanks.
Liber = Singular nominative (book is the subject); Librum = Singular accusative (book is the object); Libro = Singular dative ("in the book" or similar)
Dative ending means
To or for the book
So it doesnt matter if the speaker is male or female? "My" would be fem., masc or neut. depending on the noun "my" describes?
Yes, meus works like other adjectives in Latin and agrees in gender and number of the noun it modifies.
Just like in French; and I gues in Spanish it's the same thing? ¿ no ?
Why is "Liber meus in domo est" incorrect?
domus is noun that can use the locative instead of in with the ablative. They want you to use the Locative domi.
