== 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.
=== Pronunciation ===

== Estonian ==
=== Etymology ===
A merger of Proto-Finnic *-us (in the first sense) and Proto-Finnic *-uc (in the second sense). Cognate with Finnish -us.
=== Suffix ===
-us (genitive -use, partitive -ust)
Derives nouns from verbs.
armastama "to love" → armastus "love"
võistlema "to compete" → võistlus "competition"
joonistama "to draw" → joonistus "a drawing"
Derives nouns from adjectives.
aus "honest" → ausus "honesty"
pikk "long" → pikkus "length"
==== Declension ====
==== Derived terms ====
== Finnish ==
=== Etymology 1 ===
From Proto-Finnic *-us, partly equivalent to -u + -s, and partly 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)
Forms nouns from verbs, describing an action, event or a result of that action.
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.

===== Alternative forms =====
-tus (used with the verb types rohkaista (66) and valita (69))
===== Synonyms =====
-mus (used with the verb types sallia (61), and in some cases, sanoa (52) and muistaa (53))
===== Derived terms =====

=== 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 -us (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)
Forms nouns, indicating resemblance or association.
kanta (“base, heel”) + -us → kannus (“spur”)
sormi (“finger”) + -us → sormus (“ring”)
vasta- (“counter-”) + -us → vastus (“resistance, opposition”)
kehä (“circle, ring”) + -us → kehys (“frame”)
syli (“bosom, lap”) + -us → sylys (“armful”)
typerä (“stupid”) + -us → typerys (“fool”)

su
== Hungarian ==
=== Etymology ===
From -u (diminutive suffix) + -s (diminutive suffix).
=== Pronunciation ===
IPA(key): [uʃ]
=== Suffix ===
-us
(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”)
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.

== Latin ==
=== Etymology 1 ===
From Old Latin -os, from Proto-Italic *-os, from Proto-Indo-European *-os (adjectival ending). Cognate with Ancient Greek -ος (-os), Proto-Germanic *-az, Icelandic -ur, Sanskrit -अः (-aḥ), Proto-Slavic *-ъ.

==== Suffix ====
-us
suffix of nouns in the second declension
(chiefly) nominative singular of -us
(not productive) nominative/accusative/vocative singular of -us for second-declension neuter nouns
vīrus (“a poisonous or acrid secretion”); vulgus (“common people”); pelagus (“sea”)
suffix of adjectives in the first/second declension:
forms compound adjectives
Synonym: -is
bī- + hiems + -us → bīmus
in- + animus + -us → inanimus
forms deverbal adjectives
Synonym: -uus
invideō + -us → invidus
sonō + -us → -sonus
dīcō + -us → -dicus
(chiefly) nominative singular of -us
(New Latin) suffix used to Latinize names ending in consonants
===== Usage notes =====
For certain nouns whose roots end with the letter r, no ending is applied in the nominative and vocative singulars; instead, an e is added before the r, if there isn't one already in the root (i.e. liber (root libr-), alabaster (root alabastr-), puer (root puer-)), although some, such as the aforementioned puer, have alternative forms with regular -us and -e endings in the nominative and vocative singulars. The only irregular masculine noun in this regard is vir, whose nominative and vocative singulars would be expected to be *virus and *vire.
===== Declension =====
===== Derived terms =====
=== 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 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.

From the plural -ora:
Romanian: -uri (final vowel replaced due to analogy with feminine plural forms)

=== 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).

=== Etymology 4 ===
From Proto-Indo-European *-os, a genitive singular ending for athematic nouns (an o-grade alternative to e-grade *-es, which developed to the usual Latin third-declension genitive singular ending -is).
==== Pronunciation ====
(Classical Latin) IPA(key): [ʊs]
(modern Italianate Ecclesiastical) IPA(key): [us]
==== Suffix ====
-us
rare alternative genitive singular ending for nouns of the third declension
===== Usage notes =====
A relic form attested exclusively in inscriptions that are dated up through first-century AD graffiti in Pompeii. Its sparse attestations are not restricted to official texts: some examples are found in less elevated documents such as graffiti and pottery inscriptions. This suggests the ending may have initially survived to some extent in dialectal use. However, it may have been used as a stylistic archaism in legal contexts after it became obsolete in general. A genitive singular ending derived from *-os seems to have occurred in Faliscan as well as sporadically in Latin.

== 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.

IPA(key): /ʊs/
==== Suffix ====
-ùs m stress pattern 4
