-itus

Latin Etymology 1 la adjectival :der ine-pro:*-tós<id:verbal adjectives> From la ine-pro *-tós, suffix forming possessive adjectives from nouns (compare la -ātus), combined with preceding material of uncertain origin (different words may have different sources of -ī-). According to one hypothesis, some words ending in la -ītus are "decasuative" formations derived from former inflected noun forms that ended in -ī, such as the instrumental singular form of i-stem nouns or the genitive singular of o-stem nouns. For example, in la crīnītus long-haired, the ending la -ītus may be from instrumental *-ih₁ + *-to-.Fortson, B. W., IV. (2020). "Towards an assessment of decasuative derivation in Indo-European," Indo-European Linguistics, 8(1), 46-109. doi: https://doi.org/10.1163/22125892-bja10004 But this type of derivation is disputed. Other words may have been formed by analogy. It is often difficult to distinguish the adjectival ending from the fourth-conjugation participial ending, and in some cases fourth-conjugation verbs may have been derived from original adjectives by back-formation; for example, the occurrence of the finite verb form la crīnītur in Statius is presumably based on reinterpretation of la crīnītus as a participle.
