N-Stem Nouns

[blutoonwithcarrotandnail]

the genitive singular is a shortcut to predicting an n-stem:

HOMO
HOMONIS
HOMIN (-IS)

ORDO
ORDONIS
ORDON (-IS)

SERMO
SERMONIS
SERMON (-IS)

apparently alot of N-Stems end in -IO -TUDO -DO -GO

ORDO ends this way with -DO

can anybody give me examples of N-Stems (fem.) which end in
-IO or -TUDO or -GO?

[Damoetas]

Here are some:

possessiō, possessiōnis, f. 'possession.'

magnitūdō, magnitūdinis, f. 'size, greatness.'

rōbīgō, rōbīginis, f. 'rust.'

In the lists you gave, I would suggest that you not focus on memorizing the middle form (HOMONIS, ORDONIS), since these are forms that do not actually exist. They are reconstructions of how the words would have been pronounced at an earlier stage in the history of the language; they might be helpful in understanding where the later forms come from; but they're not words that you're ever going to see in Latin literature. So it would be better to concentrate on memorizing the paradigms that actually occur. For example:

homō
hominis
hominī
hominem
homine

Learn these until you can say them backwards and forwards, and practice reading them in context!
