222. Conjunctions, like prepositions (cf. § 219), are closely related to adverbs, and are either petrified cases of nouns, pronouns, and adjectives, or obscured phrases.
quod [an old accusative]
dum [probably an old
accusative (cf. tum, cum)]
vērō [an old neuter ablative of vērus]
nihilōminus none the less
proinde [lit.]
forward from there
Most conjunctions are connected with pronominal adverbs, which cannot always be referred to their original case forms.
