Last time, I talked about how Sine Flexione nouns are derived from the
singular ablative of the Latin language. This method is still valid,
but the table below explains how to identify the ablative with the
genitive. As we know, dictionary dictionaries provide the nominative
and genitive cases of the search word.

Nouns are formed from the Latin Genetive as Shown below

The form of nouns depends on the Latin declensions.

Those proper nouns written with the Roman alphabet are kept as close
to the original as possible. The following are examples: München, New
York, Roma, Giovanni

Adjectives
and adverbs

Adjectives are formed as follows:

• If the nominative neuter ends with -e, the Latino form is
  unchanged.
• If the nominative neuter ends with -um, the Latino form is
  changed to -o: novum > novo (new).
• In all other cases, adjectives are formed with the ablative case
  from the genitive, as is the case with nouns.

Adjectives can be used as adverbs if the context is clear, or cum
mente or in modo can be used:

• Diligente (diligent): Cum mente diligente, cum
  diligente mente, in modo diligente, in diligente modo
  = diligently.

Ablative  with
prepositions

The ablative case is very frequently used with prepositions, for
example ex urbe
“out of the city”, cum
eō “with him”. Four prepositions (in “in/into”, sub
“under/to the foot of”, subter “under”, super “over”)
may take either an accusative or an ablative. In the case of
the first two, the accusative indicates motion, and the ablative
indicates no motion. For instance, in urbe means “in the city”;
in urbem, “into the city”.^[14]
In the case of super, the accusative means “above” or “over”,
and the ablative means “concerning”.^[15]

The prepositions which are followed by the ablative case are the
following:
