---

Latin

Etymology

Via rhotacism from Proto-Italic *weisos, from Proto-Indo-European *wisós (“fluidity, slime, poison”). Cognates include Sanskrit विष (viṣá), Ancient Greek ἰός (iós), from an older form ϝἰσός : wisós; Tocharian B wase, and Middle Irish fí. The neuter gender of this term despite its nominative singular ending in the masculine second-declension -us is a relic of this term's inheritance from a neuter s-stem.

Pronunciation

• (Classical) IPA^(key): /ˈwiː.rus/, [ˈwiː.rʊs]
• (Ecclesiastical) IPA^(key): /ˈvi.rus/, [ˈviː.rus]

Noun

vīrus n sg (genitive vīrī); second declension

1. A stinking, or rammish smell.
2. The seed or nature in animals.
3. A nasty taste.
4. Poison, venom.
5. Bitterness, sharpness.
6. The juice of the purple-fish.
7. A strong smell of spices or perfumes.
8. slimy liquid, slime
9. (New Latin) virus (infectious organism)

Declension

Second-declension noun (neuter, nominative/accusative/vocative in -us), singular only.

Case	Singular
Nominative	vīrus
Genitive	vīrī
Dative	vīrō
Accusative	vīrus
Ablative	vīrō
Vocative	vīrus

• There is also the heteroclitic genitive singular vīrūs.
• When used in modern biology with the same meaning of English virus, a plural can be formed using the same suffixes of regular neuters of the 2nd. declension (i.e., vīra, vīrōrum, vīrīs, vīra, vīrīs, vīra).

Derived terms

• vīrōsus
• vīrulentus
