4.5 Comparison of adverbs

Forms of Adverbial Comparison

Latin adverbs come in three degrees, just like adjectives: positive, comparative, and superlative. These degrees let you express not just how something is done, but whether it's done more or most in that way compared to something else.

Positive Degree

The positive degree is the base form of the adverb, with no comparison involved.

• For 1st/2nd declension adjectives, add -ē to the stem: cārus → cārē (dearly)
• For 3rd declension adjectives, add -iter or -ter to the stem: fortis → fortiter (bravely); sapiēns → sapienter (wisely)

This form simply describes the manner of an action: Fortiter pugnat ("He fights bravely").

Comparative Degree

The comparative degree expresses a greater intensity and is used when comparing two actions or states.

Here's the key formation rule: the comparative adverb is identical to the neuter accusative singular of the comparative adjective. That means it always ends in -ius.

• cārē → cārius (more dearly)
• fortiter → fortius (more bravely)

A comparative adverb can also stand alone without an explicit comparison, carrying the sense of "rather" or "quite": Celerius cucurrit ("He ran rather quickly").

Superlative Degree

The superlative degree expresses the highest intensity, used when comparing three or more actions or states.

Form it by taking the superlative adjective (ending in -issimus, -errimus, or -illimus) and replacing -us with -ē.

• cārē → cārissimē (most dearly)
• fortiter → fortissimē (most bravely)

Regular Adverbial Comparison

Regular formation follows a predictable three-step pattern from the adjective:

1. Positive: adjective stem + appropriate ending (-ē, -iter, -ter)
2. Comparative: adjective stem + -ius (neuter accusative singular of the comparative adjective)
3. Superlative: superlative adjective stem + -ē (swap -us for -ē)

Common Examples

Notice that pulcher and celer form their superlatives with -errimē rather than -issimē, mirroring how their adjectives behave (pulcherrimus, celerrimus).

Irregular Adverbial Comparison

Some of the most common Latin adverbs are irregular. These don't follow the standard formation rules and need to be memorized individually.

These parallel the irregular adjectives you already know (bonus/melior/optimus, malus/peior/pessimus, etc.), so learning them as pairs helps. If you know the adjective is irregular, the adverb will be too.

Syntax of Adverbial Comparison

Comparative Constructions

There are two main ways to express "than" with a comparative adverb:

• quam + same case: Fortius quam pater currit. ("He runs more bravely than his father.") Both items being compared are in the same case (here, nominative).
• Ablative of comparison: Fortius patre currit. (Same meaning, but patre is in the ablative instead of using quam.) This construction is more concise and very common.

Superlative Constructions

• Partitive genitive (genitive of the whole): Omnium fortissimē pugnāvit. ("He fought most bravely of all.")
• quam + superlative means "as ___ as possible": Quam fortissimē pugnāvit. ("He fought as bravely as possible.") This is a very common and useful construction.
• Absolute use (no explicit comparison): Optimē sē gessit. ("He behaved extremely well.") Here the superlative simply intensifies the meaning.

Usage in Sentences

Modifying Verbs

This is the primary job of adverbs. They typically appear near the verb they modify, often just before it.

• Celeriter currit. ("He runs swiftly.")
• Fortius pugnat. ("He fights more bravely.")

Modifying Adjectives

Adverbs can intensify or qualify adjectives:

• Valdē pulcher ("Very beautiful")
• Nimis longus ("Too long")
• Magis idōneus ("More suitable")

Modifying Other Adverbs

Adverbs can layer onto other adverbs to create more precise expressions:

• Tam bene ("So well")
• Multō melius ("Much better," where multō is an ablative of degree of difference)
• Paulō post ("A little while after")

Comparison: Adverbs vs. Adjectives

Adverbial and adjectival comparison are closely related, but they serve different grammatical roles.

Similarities

• Both share the same comparative stem (-ior-) and superlative stem (-issim-, -errim-, -illim-)
• Both share the same irregular roots (bonus/bene → melior/melius → optimus/optimē)

Key Differences

• Adjectives modify nouns and must agree in gender, number, and case. Adverbs modify verbs, adjectives, or other adverbs and are invariable (they never change form to agree with anything).
• The comparative adverb uses the neuter accusative singular (-ius), while the comparative adjective declines fully (-ior, -iōrem, -iōris, etc.).
• The superlative adverb ends in -ē (fortissimē), while the superlative adjective declines like a 1st/2nd declension adjective (fortissimus, -a, -um).

Common Pitfalls

Confusing Adverbs with Adjectives

• Using an adjective ending where you need an adverb: writing pulchrus when you mean pulchrē ("beautifully"). If the word modifies a verb, you need the adverb.
• Trying to decline an adverb to match a noun: fortiter stays fortiter regardless of the gender, number, or case of anything else in the sentence.
• Translating celeriter as "swift" instead of "swiftly." Always check whether the Latin word is modifying a noun (adjective) or a verb (adverb).

Incorrect Degree Usage

• Using the comparative when the superlative is needed: omnium melius is wrong; with a partitive genitive ("of all"), you need the superlative omnium optimē.
• Using the superlative for a comparison between only two things. Two items take the comparative; three or more take the superlative.
• Forgetting quam when the second term of comparison is in the same case as the first. Without quam, use the ablative of comparison instead.

Translation Strategies

Context-Based Interpretation

A comparative adverb doesn't always mean "more ___." Without an explicit comparison, it can mean "rather" or "quite" (celerius = "rather quickly"). Similarly, a superlative used absolutely can mean "very" rather than "most."

Pay attention to surrounding constructions like quam, partitive genitives, and ablatives of comparison to determine how to translate the degree.

Idiomatic Expressions

Some adverbial phrases have set translations worth memorizing:

• quam celerrimē → "as quickly as possible"
• quam maximē → "as much as possible"
• plānē → "clearly" or "absolutely" (depending on context)

When translating into English, aim for natural phrasing. Multō fortius pugnāvit is better rendered "He fought much more bravely" than a wooden word-for-word translation.

Practice Exercises

Identification of Forms

• Given an adverb like sapientissimē, identify its degree (superlative) and its positive form (sapienter).
• In a sentence like Miles fortius quam dux pugnāvit, find the adverb, name its degree, and explain the comparison being made.

Sentence Completion

• Fill in the blank with the correct degree: Omnium ___ (bene) cantat. (Answer: optimē, because the partitive genitive omnium requires the superlative.)
• Choose between adjectival and adverbial forms: Puella ___ (pulcher) cantat. (Answer: pulchrē, because you need an adverb to modify the verb cantat.)

Translation Practice

• Latin to English: Magister sapientius quam discipulī locūtus est. ("The teacher spoke more wisely than the students.")
• English to Latin: "She ran as quickly as possible." (Quam celerrimē cucurrit.)
