Esperanto

Etymology

The Esperanto suffixes -as, -is, -os, and -us are related and appear to have been inspired by previous language projects:

This play of vowels is not an original idea of Zamenhof's: -as, -is, -os are found for the three tenses of the infinitive in Faiguet's system of 1765; -a, -i, -o without a consonant are used like Z's -as, -is, -os by Rudelle (1858); Courtonne in 1885 had -am, -im, -om in the same values, and the similarity with Esperanto is here even more perfect than in the other projects, as -um corresponds to Z's -us. —An International Language (1928)

In addition, the u of -us is likely to be related to -u.

Finnish

Etymology 1

From Proto-Finnic *-us, generalized from -s-derivatives of u-stem verbs (e.g. ihastua → ihastus, menestyä → menestys). Compare -os.

Suffix

-us (front vowel harmony variant -ys, linguistic notation -Us)

1. Forms nouns from verbs, describing an action or event.

   ‎kuvata (“to describe”) + ‎-us → ‎kuvaus (“description”)

   ‎pakata (“to pack”) + ‎-us → ‎pakkaus (“package”)

   ‎ylentää (“to promote”) + ‎-us → ‎ylennys (“promotion”)

   ‎hälyttää (“to alarm”) + ‎-us → ‎hälytys (“alarm”)

Usage notes

• With -ahtaa (momentane) verbs, the final -ht- may disappear entirely (through *-AhdUs > *-AhUs (regular loss in e.g. eastern dialects) > *-AUs). This has led to -AUs (-aus/-äys) becoming its own pseudo-suffix. Often both variants, one with -AhdUs and one with -AUs, exist in parallel.

Derived terms

Finnish terms suffixed with -us (action or event)

Etymology 2

From Proto-Finnic *-us. Probably generalized from -s-derivatives of u-stem nominals (e.g. etu- → edus, palvelu → palvelus), or through the loss of a plain u-derivative from the standard language (e.g. keski- → dial. kesku- → keskus), and thus identical to etymology 1. In some cases potentially by confusion with -uus, -us (etymology 3). Alternatively from Proto-Uralic *-wikse.

Suffix

-us (front vowel harmony variant -ys, linguistic notation -Us)

1. Forms nouns, indicating resemblance or association.

   ‎kanta (“base”) + ‎-us → ‎kannus (“spur”)

   ‎sormi (“finger”) + ‎-us → ‎sormus (“ring”)

   ‎vasta- (“counter-”) + ‎-us → ‎vastus (“resistance, opposition”)

Etymology

From -u (diminutive suffix) +‎ -s (diminutive suffix).

Pronunciation

• IPA^(key): [uʃ]

Suffix

-us

1. (diminutive suffix) Added to a proper noun or other nouns to create a diminutive noun.

   Teréz (“Theresa”) → Terus (“Tess”)

   apa (“father”) → apus (“dad”)

   cica (“cat”) → cicus (“kitty”)

   kutya (“dog”) → kutyus (“pooch, puppy”)

2. A distinguishable foreign word ending in nouns. It cannot be considered as an independent Hungarian suffix.

   agronómus (“agronomist”)

Usage notes

• (diminutive suffix): It creates diminutive or affectionate forms, most of the time of people’s given names, but also of common nouns, usually from ones ending in -a. Other examples: Anna → Annus, Magda → Magdus, Gyula → Gyulus. The -ka diminutive suffix can also be appended after -us to further increase the degree of endearment: apuska, cicuska, kutyuska, Annuska, Magduska.

Etymology 2

Generally from Proto-Indo-European *-os (suffix forming neuter s-stem nouns from verbs), as in genus n from *ǵénh₁os n (“race”). Not a productive derivational suffix in Latin. The plural and oblique case forms have -r- as the result of the sound change of rhotacism. Additionally, in many words, the oblique stem has the vowel -ĕ- (as in generis), which is generally taken to be the phonetically regular development of the Proto-Indo-European forms. Some words, such as as decus, decoris, instead have -ŏ- in the oblique stem; this is the result of analogical introduction of the rounded vowel from the nominative/accusative singular form.

Etymology 3

Not a single suffix, but an ending of various miscellaneous origins. In most words, from Old Latin -us, from Proto-Italic *-us, from Proto-Indo-European *-us as the final part of Proto-Indo-European *-tus (suffix deriving action nouns from verb roots).

Lithuanian

Etymology 1

Ultimately from Proto-Indo-European *-ós (“adjectival ending”). Pairs such as lañkas (“bend”) : lankùs (“flexible”) find parallels in Sanskrit रुधिर (rúdhira-, “blood”) : रुधिर (rudhirá-, “red”), Ancient Greek δόλιχος (dólikhos, “a long run”) : δολιχός (dolikhós, “long”) and suggest that oxytone stress was used to mark adjectives in Proto-Indo-European. In Proto-Balto-Slavic, the raising of *o to *u must have been conditioned by stress, with the ending *-os giving Lithuanian -ùs under stress and -as otherwise.

Pronunciation

• IPA^(key): /ʊs/

Suffix

-ùs m stress pattern 4

1. Adjectival suffix, applied to verbal and nominal roots to denote a disposal or tendency towards something
