Adverbs

The Superlative Adverb

The superlative form of an adverb is extremely simple. It has exactly the same stem as the superlative adjective and it always ends in -ê.

Positive adjective	Superlative adjective	Positive adverb	Superlative adverb
clarus, -a, -um, clear	clarissimus, -a, -um, most clear	clarê, clearly	clarissimê, most clearly
levis, levis, leve, light	levissimus, -a, -um, very light	levê, lightly	levissimê, very lightly
celer, celeris, celere, swift	celerissimus, -a, -um, swiftest	celeriter, swiftly	celerissimê, most swiftly
prudens, prudentis, wise	prudentissimus, -a, -um, very wise	prudenter, wisely	prudentissimê, very wisely
[none]	[none]	diû, for a long time	diûtissimê, for a very long time
[none]	[none]	saepe, often	saepissimê, most often

Like superlative adjectives, superlative adverbs can have more than one possible meaning. For instance,

lentissimê = "most slowly" or "very slowly"

When a superlative adverb is used with quam it has a special meaning: "as _____ as possible":

Tabellarius cucurrit quam celerissimê = the messenger ran as quickly as possible
