-ter (genitive -terī or -trī; feminine -tera or -tra, neuter -terum or -trum); adjectival suffix[2]
Etymology
The suffix for contrastive adjectives is inherited from Proto-Indo-European *-tero-, which Sihler and Fortson take as a contrastive suffix, typical at first of adverbs and pronouns and added to stems.[3][4] Sihler gives the example of *kʷo-tero- “which of two?” beside *kʷo- “which”.[3] Weiss derives uter from *kʷu-teros.[5]
Cognate with Ancient Greek -τερος (-teros) and Sanskrit -तरः (-taraḥ).[2] The original force was not intensive: Sihler points out that δεξιτερός (dexiterós) “right” meant the one opposed to the left, and dexter is compared with it.[3][2]
Earliest recorded meaning
Livius Andronicus has dextrābus, a form of dexter.[2] Plautus has alter, in the Trinummus.[2]
Semantic evolution
In Latin it is often found in opposing pairs: magister and minister, noster and vester, dexter and sinister.[2] From this it gave words for one of two, as alter and uter, and it also appears in dēterior, posterī and cēterī.[2] Fortson counts that comparative among its continuations, beside the comparative suffixes of Sanskrit and Greek.[4]

Pronunciation
Forms
-ter (comparative -ius, superlative -issimē)[1]
Etymology
The suffix for adverbs is perhaps ultimately from Proto-Indo-European *-teros, from the nominative masculine singular of contrastive adjectives, or perhaps extended from the ending of prepositions such as inter and praeter.[1] Weiss states that no theory of it is agreed on and gives the same two views.[5]
The full form ⟨-iter⟩ appears as -ter in audācter, by syncope from ⟨*audakiter⟩, and in stems in -nt-, by haplology, as dīligenter from ⟨*diligentiter⟩.[5]
Earliest recorded meaning
Livius Andronicus has aequiter “fairly” in a tragedy.[5] Ennius has audācter “boldly” in the Annals.[2]
Semantic evolution
It became the regular adverbial suffix of third-declension adjectives.[2][5] In Old Latin, and rarely later, it was also added to second-declension adjectives, as ampliter and hūmāniter.[2][5] These forms enjoyed something of a resurgence in Late Latin.[5] The adverb of alius is always aliter.[5]
Timeline
- 280–200 BC – Livius Andronicus has aequiter.[5][6]
- 204–169 BC – Ennius has audācter.[2][6]
- c. 35–95/96 AD – Quintilian calls the analogically recreated form audāciter pedantic.[5][6]
Meanings
Suffix
- Forms adverbs from adjectives, regularly from the third declension, like English -ly: audācter, fortiter, prūdenter; also, especially in Old Latin, from the second: hūmāniter.[2][1]
