The adjective "omnis, -e" is a third declension adjective of two terminations. This means it has one form for masculine and feminine (omnis) and another for neuter (omne) in the nominative singular.
Declension of omnis, -e:
Singular: -
Nominative: omnis (m./f.), omne (n.) -
Genitive: omnis (all genders) -
Dative: omnī (all genders) -
Accusative: omnem (m./f.), omne (n.) -
Ablative: omnī (all genders)
Plural: -
Nominative: omnēs (m./f.), omnia (n.) -
Genitive: omnium (all genders) -
Dative: omnibus (all genders) -
Accusative: omnēs (m./f.), omnia (n.) -
Ablative: omnibus (all genders)
Step-by-Step Guide to Using omnis: -
Identify the noun it modifies (gender, number, case) -
Match omnis to agree in gender, number, and case -
Remember: omnis can precede or follow its noun -
With singular nouns = "every" or "each" -
With plural nouns = "all" collectively
Common Mistakes: -
Confusing with totus: Students often confuse omnis with totus. Totus means "the whole of" (one complete thing), while omnis means "all" or "every" (multiple things or each individual thing). -
Wrong case endings: Mixing up third declension endings with first/second declension adjective endings. Remember: omnis uses -ī in dative/ablative singular, not -ō/-ā. -
Genitive plural confusion: The genitive plural omnium is often mistaken for a neuter plural form. It's actually genitive for all genders. -
Meaning with singular nouns: Forgetting that omnis + singular noun usually means "every" not "all." Example: omnis miles = every soldier, not all soldiers.
Comparison with English:
Unlike English, where "all" and "every" are separate words, Latin uses omnis for both concepts, distinguished by the number of the noun: -
omnis mīles = every soldier -
omnēs mīlitēs = all soldiers
English word order is more rigid ("all soldiers"), while Latin can place omnis before or after the noun for emphasis.
Grammatical Summary:
Type: Third declension adjective of two terminations Stem: omn- Key forms to memorize: -
Nom. sing.: omnis/omne -
Gen. plural: omnium -
Dat./Abl. plural: omnibus Agreement: Must match its noun in gender, number, and case

For Roman military commanders, the concept of "omnis" held special significance in warfare and strategy. The phrase "omnēs mīlitēs" (all soldiers) represented not just a numerical total but the unified fighting force of Rome. Military discipline demanded that when an order affected "omnēs," every single soldier was expected to comply without exception.
In naval contexts, "omnibus vēlīs" (with all sails) was a technical term indicating maximum speed - a crucial tactical decision that could mean the difference between catching an enemy fleet or losing them beyond the horizon. Roman naval commanders understood that deploying "all sails" also meant increased vulnerability to sudden weather changes.
The expression "omnibus partibus" (on all sides) frequently appears in siege warfare accounts. Roman military engineering excelled at surrounding enemy positions completely, and when a commander reported that fortifications were "omnī parte mūnīta" (fortified on every side), it signified an impregnable defensive position.
Military supply officers paid particular attention to "omnium rērum" (of all things) in their inventories. The Roman military's success depended on comprehensive logistics - ensuring that every necessary item, from grain to replacement weapons, was accounted for and distributed.
The concept extended to time as well: "omnibus diēbus" (every day) described the relentless Roman training regimen that transformed farmers into professional soldiers. This daily discipline distinguished Roman forces from many of their opponents who might only train before campaigns.
Understanding "omnis" helps modern readers appreciate how Romans thought about military completeness and thoroughness - values that contributed to their centuries of military dominance.

From Caesar's De Bello Gallico 1.2:
Apud among Helvētiōs the Helvetii longē by far nōbilissimus the most noble fuit was et and dītissimus richest Orgetorīx. Orgetorix. Is He rēgnī of royal power cupiditāte by desire inductus led coniūrātiōnem a conspiracy nōbilitātis of the nobility fēcit made et and cīvitātī to the state persuāsit persuaded ut that dē from fīnibus territories suīs their own cum with omnibus all cōpiīs forces exīrent: they should go out: perfacile very easy esse, to be, cum since virtūte in valor omnibus all praestārent, they excelled, tōtīus of the whole Galliae of Gaul imperiō by command potīrī. to gain control.
Apud Helvētiōs longē nōbilissimus fuit et dītissimus Orgetorīx. Is rēgnī cupiditāte inductus coniūrātiōnem nōbilitātis fēcit et cīvitātī persuāsit ut dē fīnibus suīs cum omnibus cōpiīs exīrent: perfacile esse, cum virtūte omnibus praestārent, tōtīus Galliae imperiō potīrī.
Among the Helvetii, Orgetorix was by far the most noble and wealthy. Led by desire for royal power, he made a conspiracy of the nobility and persuaded the state that they should leave their territories with all their forces: that it would be very easy, since they excelled all in valor, to gain control of the whole of Gaul.
Apud Helvētiōs longē nōbilissimus fuit et dītissimus Orgetorīx. Is rēgnī cupiditāte inductus coniūrātiōnem nōbilitātis fēcit et cīvitātī persuāsit ut dē fīnibus suīs cum omnibus cōpiīs exīrent: perfacile esse, cum virtūte omnibus praestārent, tōtīus Galliae imperiō potīrī.
In this passage, Caesar uses "omnibus" twice with different grammatical functions: -
"cum omnibus cōpiīs" - Here omnibus is in the ablative plural, modifying cōpiīs (forces). The construction "cum + ablative" indicates accompaniment: "with all their forces." This usage emphasizes the total military commitment Orgetorix proposed. -
"virtūte omnibus praestārent" - Here omnibus is a dative plural used with the verb praestō (excel, surpass). The dative indicates those whom they surpass: "they excelled all (others) in valor." This is a common construction with verbs of excelling or surpassing.
Note how Caesar contrasts "omnibus" (all others) with "tōtīus Galliae" (of the whole of Gaul), showing the Helvetii's ambition to dominate not just some, but absolutely all of Gaul. The military context makes clear that "omnibus cōpiīs" refers to complete mobilization - not just warriors but the entire population prepared for migration and conquest.

This military dispatch section demonstrates advanced uses of "omnis" in professional military Latin:
1. Direct Speech (18.16): "Omnēs legiōnēs parātae sunt" - Note the word order in official reports: the comprehensive "omnēs" leads for emphasis, followed by subject and predicate. This is typical of military status reports.
2. Passive Voice Constructions: -
"vīsae sunt" (were seen) - 18.17 -
"distribūtum est" (was distributed) - 18.23 -
"īnstrūcta est" (is equipped) - 18.29 These passive constructions are characteristic of military dispatches, focusing on actions completed rather than actors.
3. Ablative of Means/Instrument: -
"omnibus vīribus" (with all strength) - 18.21 -
"omnibus rēbus necessāriīs" (with all necessary things) - 18.29 The ablative with omnis frequently expresses total resource commitment.
4. Partitive Genitive: -
"omnium mēnsium" (of all months) - 18.20 -
"omnium mīlitum" (of all soldiers) - 18.30 These show comparison or source among a complete group.
5. Locative Expressions: -
"omnibus collibus" (on all hills) - 18.18 -
"omnī parte" (on every side) - 18.28 Military Latin uses these to describe comprehensive tactical positions.
6. Word Order Variations: Compare: -
"Omnēs legiōnēs" (all legions) - emphasis on totality -
"Hostium omnēs cōpiae" (enemy's all forces) - emphasis on enemy -
"Nāvēs omnēs" (ships all) - emphasis on ships
Technical Military Terms with omnis: -
omnēs legiōnēs - complete legionary force -
omnēs centuriōnēs - full officer corps -
omnēs viās - all supply/communication routes -
omnia arma - complete arsenal inspection
These constructions show how Roman military writers used "omnis" to convey complete information essential for command decisions.
