"Her mother has a grave."
Translation:Mater eius sepulchrum habet.
eius is the genitive or possessive case of is, ea, id (he, she, it) for all three genders. It means "of him" "of her" or "of it" or more usually, "his," "her," "its." Thus "mater eius" = "his mother" (or "her mother", or "its mother"). In the plural "their mother" would be "mater eorum" or "mater earum" depending on whether the children are boys or girls. If a mixture, Latin would use the masculine form.
Would "mater illius sepulchrum habet" be correct as well? I was wondering, because the app tells me that it's wrong, but in other sentences both the forms of is/ea/id and ille/illa/illud are correct as a personal pronoun. Is there a difference between using is/ea/id and ille/illa/illud? Thanks in advance for your help!
The "her/his" form is Eius (/ejus).
Eius is a pronoun in genitive singular.
"Ei" is a form of "Is".
-nominative masculine plural of is (=they)
-dative masc, fem and neut. sing. of is (to him, to her, to it)
Maybe they meant "to her" instead of "her" (would probably better to list it as a "to her), but the dative form in Latin could also be translated as the direct pronoun "her" in English, in some sentences (many of them), because a verb could be transitive in a language and intransitive in another one...
Also a demonstrative (because of the use of "is" as personal pronoun or as a demonstrative).
Ei homines = These men.
Illam is a demonstrative.
Singular acc. feminine for "ille".
As demonstrative are also used to mean personal pronoun, it could probably also be a "her" if they listed it in their dictionary.
Sepulcra/ sepulchrum I'm very confused here. Sepulcr is a neuter noun in both nominative and accusative endings. And because it is a neuter word and its plural, they both end in 'a'? Is this an educated way of saying that plural is sepulcra and sungular is sepulcrum? Or am I way out in left field?
"sua" is the emphatic "eius", it means "her own".
So, it's not right here.
You would use it when it's not natural that you have to use the simple personal pronoun, like in "I am my own doctor" instead of "I am my doctor".
The pronoun (is, ea, id) has the same genitive for all three genders.
Please see the explanation by Perce_Neige above, from 1 year ago: "The "her/his" form is Eius (/ejus). Eius is a pronoun in genitive singular.
"Ei" is a form of "Is". -nominative masculine plural of is (=they) -dative masc, fem and neut. sing. of is (to him, to her, to it) ...."
