ok, it's time for me to five you some grammar. Here I go:
Latin knows 5 different tpyes of substantiva. The nominativus, the accusativus, the genitivus, the dativus and the ablativus. Then there are 2 different subtypes, plural and singular. Then we have 3 different subsubtypes: neuter, masculine and feminine.
Here, we have a list of the things I just explained.
-----------| S | P |
-----------| M | F | N | M | F | N |
Nominativus|avUS|rosA |donUM|avI |rosAE |donA |
Accusativus|avUM|rosAM|donUM|avOS |rosAS |donA |
Genitivus--|avI |rosAE|donI |avORUM|rosARUM|donORUM|
Dativus----|avO |rosAE|donO |avIS |rosIS |donIS |
Ablativus--|avO |rosA |donO |avIS |rosIS |donIS |
What can clearly be seen is that substantivos are devided into three catogories: M, F and N. These cannot be changed.
What can be changed are the number and the <things, dont know the word :S>. Substantivi are always shown in the nominativus, unless placed in a sentance.
The next part of a basic sentance (and I mean very basic).
The verbs, present simple I believe (you're gonna have to correct me at those times, HH.)
[list]laborare is the verb, it means: to work
laboram = I work
laboras = you work
laborat = he/she/it works
laboratis = you work
laborant = they work[/list:u]
Now translate this sentance:
avus laborat. (avus means grandfather)
