-ittus

Latin Alternative forms la -ettus Etymology la diminutive :der itc-pro:*-tos<unc> la. Perhaps doublet (with the littera littera rule) of la -ītus, from la itc-pro *-tos. It COULD just be an alteration of -illus, -ellus, or simply -lus, but this hypothesis would not work out well, and neither l → t nor ll → tt are documented for PIE to Latin in the Index Diachronica (plus, the ID doesn't even have sound changes from Latin to Latin, so that wouldn't work anyway). It could just be an irregular sound change, however, or it could just be inspired by it in shape or form. This change is, also, not documented in the section "Classical Latin vs. Vulgar Latin," respectively for older Romance languages such as Old French and Old Spanish. Pronunciation la diminutive suffixes Suffix -ittus diminutive suffix, used to create nouns Usage notes Attested in the female form in proper nouns of the Imperial period.
