FORMATION AND COMPARISON OF ADVERBS.

76. Adverbs are for the most part derived from adjectives, and depend upon
them for their comparison.

1. Adverbs derived from adjectives of the First and Second Declensions form
the Positive by changing -ī of the Genitive Singular to -ē; those derived
from adjectives of the Third Declension, by changing -is of the Genitive
Singular to -iter; as,--

cārus, cārē, _dearly_;
pulcher, pulchrē, _beautifully_;
ācer, ācriter, _fiercely_;
levis, leviter, _lightly_.

a. But Adjectives in -ns, and a few others, add -er (instead of -iter),
to form the Adverb; as,--

sapiēns, sapienter, _wisely_;
sollers, sollerter, _skillfully_.

Note audāx, audācter, _boldly_.

2. The Comparative of all Adverbs regularly consists of the Accusative
Singular Neuter of the Comparative of the Adjective; while the Superlative
of the Adverb is formed by changing the -Ä« of the Genitive Singular of the
Superlative of the Adjective to -ē. Thus--

(cārus) cārē, _dearly_, cārius, cārissimē.
