Morphology
1) Calculation of the ratio ‘Total number of prepositions in a single text / Governed cases’. This indicates how many prepositions govern the accusative, how many the ablative and how many the genitive.
2) Calculation of the ratio ‘Total number of prepositions / sentences (verbs) and words’. When prepositions don’t govern the case expected according to classical grammatical rules, the real case that occurs has been considered (e.g. cum duas filias is preposition with accusative).
3) Ratio Prepositions/Verbs: verbs are considered, besides the finite moods, also joint participles and ablative absolutes, gerunds and gerundives with final value; participles, infinite and substantive gerunds or gerunds with evident adjectival value are not considered. An auxiliary verb + infinite has been counted as independent from the governing verb only in the case of an objective clause or final value.

Syntax
1) Subject/Verb Separation: shows the ratio ‘Total words between subject and its verb / Total number of the expressed verbs’. Participles and indefinite moods are generally considered only when they have verbal function. If there are more subjects, the calculation starts from the last one; if there are more verbs (e.g. modal verbs + infinite), the last one has been considered. The –que participle is not counted as an independent word.
2) Noun/Adjective/Participle Separation. The data have been obtained by dividing the number of words that separate nouns from their adjectives (or participles) by the tTotal number of nouns involved. Where there are more adjectives or participles, thea average number is considered. The –que participle is not counted as an independent word as well.
3) SN2 (direct object) / Verb Ratio. The position of the direct objects (only nouns, not their adjectives or participles) in relation to the verb of the sentence: how many times the accusative is placed before, how many times it is postponed and how many times detached (that is separated by more than one word). The inner accusatives, the motion accusatives andor the accusatives that are subjects of an infinitive sentence are not counted.
4) SN3 (dative/ablative cases) / Verb ratio: the position of the non-direct complements without preposition, with the exception of connected adjectives or participles, in relation to the governing verb: how many times it is situated before or after and how many times separated from the verb by one or more words. Ablative absolutes are not considered.
5) SN4 (genitive) / Nouns ratio: the position of the genitive (only the substantive) in relation to its noun: how many times before, how many times after, and how many times separated by one or more words.
