-iter

From Latin -iter.

-iter

1. used to form adverbs (not productive; often present in terms derived from Latin)

• idealiter, percentualiter, prozentualiter
• Derived from Latin: adverbialiter, conditionaliter, generaliter, impersonaliter, konditionaliter, obiter, pronominaliter, realiter, simpliciter, specialiter, totaliter

• -ter

Perhaps ultimately from the nominative masculine singular of oppositional adjectives in Proto-Indo-European *-teros; perhaps extended from the suffix in prepositions like inter, praeter.

• (Classical) IPA^(key): /i.ter/, [ɪ.tɛr] (stressed on the antepenult)

-iter (comparative -ius, superlative -issimē)

1. -ly; used to form adverbs from adjectives.

The suffix -iter is usually added to a third-declension adjective stem to form an adverb of manner.

Examples:

adverbiāliter (“adverbially”), from adverbiālis (“adverbial”)

celeriter (“swiftly, immediately”), from celer (“fast, swift”)

fortiter (“strongly, powerfully”), from fortis (“strong, powerful”)

nātūrāliter (“naturally”), from nātūrālis (“natural”)

The suffix -iter was sometimes added to a second-declension stem, although -ē and -ō were more commonly used in such situations.

Examples:

avāriter (“greedily”), from avārus (“greedy”)

circiter (“round about”), from circus (“circle”)

dūriter (“roughly, harshly”), from dūrus (“rough, harsh”)

• (-ly): -ē, -er, -ō

• Latin words suffixed with -iter
