Penetratione

Penetratione is a Latin grammatical form, the ablative singular of the noun penetratio, meaning "penetration" or "entry." In classical and later Latin texts the ablative case expresses a range of relationships such as means, manner, cause or accompaniment, so penetratione would typically be translated as "by/with/through penetration" or "in regard to penetration" depending on context.

The root penetratio derives from the verb penetrare, "to penetrate" or "to enter into," and the form penetratione appears in legal, theological and technical writings where authors describe acts of entry, influence, or the passage of substances. It also occurs in medieval and ecclesiastical Latin usages, where precise case endings are maintained for syntactic clarity. As an isolated form it is most often encountered in phrases rather than as a standalone lemma.

In modern languages the semantic field of penetratio is reflected in words such as English "penetration" and Italian "penetrazione"; penetratione itself is not standard in contemporary Italian, where penetrazione is used. When encountered in modern texts, penetratione is usually either a retained Latin inflection in scholarly or liturgical contexts or a typographic or orthographic variant. Understanding penetratione therefore requires basic knowledge of Latin morphology and the syntactic roles of the ablative case.
