I learned ντομάτο. Referring to this answer you can also leave the 'ν'?
Ντομάτα. starting with ν- is in fact the most common term, ending in α, though, not in -ο. Ντομάτο is not a word. :)
Ιn my (dutch) dicτionnary it says το ντομάτα, not η, so this is a mistake?
Yes, it's a mistake.
If we have 'τομάτα' shouldn't we have 'αυτές' instead of 'αυτοί'? Because 'αυτοί' is masculine and doesn't agree with the feminine 'τομάτα' ? Thanks.
They (the men) have a tomato=Αυτοί έχουν μια τομάτα. They (the women) have a tomato=Αυτές έχουν μια τομάτα.
In this sentece αυτοί and τομάτα are not related in any way grammatically.
Why is the correct answer "αυτα" ?
It depends on the gender of the owner. If this noun is neutral i.e. τα παιδιά, yes
Can someone please try and explain to me the difference between μια and ενα? In what context should either be applied? I'm so confused by something that is probably quite simple. Βοήθεια!
Ένα applies to neuter nouns, whereas μία is the feminie form of the indefinite article. So μία γυναίκα=a woman, ένα παιδί=a child.
Notice that physical gender does not (always) match grammatical gender.
